Do not let a game booster close applications needed for security, accessibility, input devices, communication, recording or the game's own launch and authentication. Build a protected-app list before enabling automated closure, save work and test only optional workloads whose purpose you understand.
- A game booster should close selected optional apps, not every process outside the game.
- Protect security, accessibility, input, voice and recording tools you actually need.
- TSW Gateway describes chosen-app closure in its FiveM session workflow; inspect the selection first.
- An application reopening later does not guarantee recovery of unsaved work.
- A smaller process count is not a measured performance result.
Which background apps should a game booster not close?
Keep applications whose functions belong in your actual gaming session. A voice client is not unnecessary if you use team communication, and a capture tool is not unnecessary if recording is the purpose of the session. Classify by function rather than by whether the application itself is a game.
Start with the PC optimization buying checklist. Review the tool's selected actions before accepting its preset. Automatic does not mean that the application can decide which of your work, communication and accessibility needs matter.
| Application category | Best action | Why it matters | Limit to check |
|---|---|---|---|
| Security and managed-device tools | Preserve required protection | Security remains necessary during games | Do not bypass organization policies |
| Accessibility software | Keep required functions active | Input and output access depend on the user's setup | Confirm with the person using the device |
| Input and device controls | Identify their role before closure | Keys, profiles or peripherals can depend on them | Not every utility is required for every device |
| Voice communication | Preserve when used in the session | Team communication is part of play | Optional only when you do not need it |
| Capture and audio tools | Preserve when recording or streaming | Their workload serves the session's goal | Test the full production configuration |
| Optional personal apps | Save and close normally when appropriate | Reduces an identified competing workload | Unsaved work needs independent protection |
Why this matters
A session optimizer trades repeated manual preparation for a selected list of automatic actions. The list is the important part. A wrong selection can remove the exact functionality you intended to use during the game.
Microsoft's performance guidance recommends closing unused applications and inspecting resource use. It does not recommend treating every unfamiliar process as unused. For a 2026 configuration, preserve that distinction before using an aggressive cleanup preset.
Build a protected list before a closure list
Write down what must work during the session. Include anything needed to communicate, control the game, record the experience and maintain device security. This is a requirements list, not an attempt to keep every installed application open.
Then identify the optional apps separately. If the purpose of a process is unknown, investigate before changing it. The absence of a familiar brand name does not make a component safe to terminate.
Use these questions:
- What function does this application provide?
- Do I need that function during play?
- Does another required application depend on it?
- Is there unsaved work associated with it?
- Can I close and reopen it normally?
- What behavior will I test afterward?
Keep the answers with the device name. A shared computer can serve someone else's workflow, and a personal preference does not authorize removing their required function. Ask before changing a shared or managed configuration.
Preserve security and organization-managed controls
Keep antivirus and firewall protections enabled. An application being reversible does not make disabling protection harmless. Exposure while a setting is off does not disappear because it is later restored.
TSW Gateway confirms that Tweaks V2 Extreme mode disables Defender and Windows Firewall. Do not select those actions for a security-preserving performance test. That product-specific behavior should remain explicit rather than hidden behind a general safe or reversible label.
For your 2026 session list:
- Keep required antivirus protection active.
- Keep the firewall enabled.
- Preserve device-management software.
- Respect work or school requirements.
- Investigate a new security warning rather than dismissing it.
Do not add broad exclusions or bypass warnings simply to run an optimizer. A vendor's performance claim is not authorization to weaken a managed device. Choose another supported workflow if the requested action conflicts with required protection.
Keep accessibility applications active
Accessibility tools can be fundamental to input, reading, communication or interaction. A closure list that removes them can make the game or desktop unusable. Their necessity is determined by the user's actual needs, not by a generic optimizer profile.
Confirm the required functions before testing. Preserve the software supporting those functions and ask the person using the computer to verify that the session remains accessible. Do not assume that a game launching proves success.
Test practical behavior:
- Can the user navigate the game and menus?
- Does the required input method still work?
- Is needed audio or visual assistance present?
- Can the user exit and recover normally?
For a 2026 setup, keep this acceptance test next to the performance test. A measured gain that removes essential access fails the purpose of optimization. Restore the relevant selection instead of asking the user to work around it.
Review peripheral utilities by their actual function
A keyboard, mouse, controller or audio utility can support more than a decorative interface. Identify whether it provides an active profile or function you use. Do not disable it because its name looks unrelated to the game.
The opposite assumption is also unhelpful: not every utility needs to remain open on every setup. Check the manufacturer's current documentation and test a normal closure when the program is genuinely optional. Keep the decision device-specific.
Before changing the session list:
- Record the active device profile.
- Identify the features used during play.
- Save the original closure or startup selection.
- Test the intended configuration.
- Verify keys, controller behavior and audio.
An app reopening afterward does not prove it served the required function while absent. Test the actual gameplay behavior. Keep a clear route back when a profile or key function stops working.
Preserve voice communication when teamwork requires it
Voice chat is part of many gaming sessions. Closing it can reduce background work while making the real session worse. That is not a useful optimization if communication matters to the game you play.
Choose a test that matches your actual use. If you normally keep a voice call open, retain it in the baseline and optimized runs. A test without it answers a different question and must be labeled accordingly.
For your 2026 record, check both listening and speaking. Verify the selected microphone and output device after app management changes. A voice window opening does not establish that the correct audio path works.
Close a communication app only when you have intentionally chosen a session that does not need it. Save messages or associated work where appropriate. Keep that decision separate from a generic close-all rule.
Preserve recording, streaming and audio routing
A session intended for clips or broadcasting must include the required capture workload. Closing the capture app can make gameplay faster while producing no recording. That result fails the stated requirement.
OBS documents that scene composition itself requires GPU resources. Treat the combined game-and-capture workload as the baseline when recording matters. If it overloads the system, diagnose relevant game or capture settings instead of removing the output entirely and calling the experiment a win.
Keep these functions in the acceptance check:
- A recording starts and stops correctly.
- Game video reaches the saved file.
- Required microphone audio is present.
- Application audio reaches the intended track.
- Normal scene or source transitions still work.
A 2026 performance verdict should describe what the saved output contains. Review the actual recording, not just the game counter. Audio and video failures often escape a test focused on average FPS alone.
Save work before any automatic closure
A request to close an application and forced process termination are different operations. Do not assume every selected app receives unlimited time to save. Read the product's documented behavior and protect your work first.
TSW Gateway's FiveM description says chosen apps are asked to close and can be ended after 3 seconds. It also describes optional reopening after play. That is a documented product behavior, not a guarantee that a document or browser task will be restored without loss.
Before a session:
- Save documents and project files.
- Finish or pause transfers through their supported controls.
- Close unnecessary browser work deliberately.
- Review the selected app list.
- Verify what automatic reopening covers.
Treat the 3-second behavior as a warning to prepare, not a universal specification for every booster. Another product can behave differently. Read the actual selection and documentation rather than transferring one tool's claim to the whole category.
Compare manual and automated preparation
| Method | Best for | Advantage | Limitation |
|---|---|---|---|
| Manual closure | A few known optional apps | Direct control and visible prompts | Preparation must be repeated |
| Selected session closure | Repeated, understood preparation | Can organize a consistent app list | A wrong selection repeats the same mistake |
| Startup changes | Persistent unwanted sign-in activity | Built-in Windows controls | Different from temporary session management |
| Broad unknown-process cleanup | Not recommended | No demonstrated requirement here | Required functions and recovery remain unclear |
TSW Gateway's game booster workflow suits players who want selected session preparation with required applications protected. Its advantage is a documented list and supported configuration history. Its limitation is that the player still must choose what is optional and protect unsaved work.
The TSW FiveM Optimizer product page documents the relevant session behavior. TSW Gateway's FiveM features should not be described as identical to every mode of Tweaks V2. Keep the product and action tied to the actual claim.
Test whether closing an app helps
Use the same game scene before and after closing one identified optional app. A practical starting procedure uses a 60-second capture repeated 3 times per configuration. These are suggested conditions, not a statistical guarantee or measured gain.
Record the app's activity, the observed result and any lost functionality. If the result is not repeatable, do not permanently remove the app based on a favorable single run. Restore the normal workflow and investigate a different cause.
For a 2026 verdict, state whether the result applies to your normal session or an intentionally stripped-down one. That makes the advice useful to someone comparing it with their own needs. A narrower true claim beats a general faster-PC promise.
Related questions
Should I close an unfamiliar process?
Identify it first. Unknown purpose is a reason to investigate, not an instruction to terminate it. Use official documentation or appropriate support when the role remains unclear.
Does reopening an app restore unsaved work?
Do not assume it does. Save work independently before closure and verify the relevant product's behavior. A new process is not evidence that the previous document state survived.
Should everyone use the same protected-app list?
No. Accessibility, devices, communication and capture needs differ. Standardize the review process rather than copying another person's requirements.

FAQ
What should a game booster never close automatically?
Protect required security, accessibility, input, voice, capture and launch functions. Decide by your actual session rather than a generic process list.
Should I let a booster close voice chat?
Keep voice chat open when communication is part of the session. Test the workload you actually use.
Can reopening restore unsaved work?
Do not rely on it. Save work before any automatic closure and check the documented behavior.
Does TSW Gateway close every background app?
TSW Gateway's FiveM description discusses apps you choose. Inspect the exact selection rather than assuming an indiscriminate close-all workflow.
Does fewer processes mean more FPS?
Not by itself. Judge repeated gameplay results and required functionality, not process count alone.
Should I turn off security for a cleaner session?
No. Keep Defender and Windows Firewall enabled, including when evaluating TSW Gateway or another tuning tool.
One last thing
Test the exit path too. A good session workflow returns the functions you need afterward, not merely a desktop that looks quiet while the game runs.
