01.What Does Game Mode Actually Do?
When you enable Game Mode (Settings > Gaming > Game Mode), Windows does two main things: 1) It pauses Windows Update and driver installations to avoid disk usage, and 2) It gives "High" priority to CPU cores for the active window process (the game), diverting resources away from Chrome tabs and Spotify.
🎮 Voltris Game Booster
Windows Game Mode is subtle. Voltris Optimizer is aggressive. It doesn't just prioritize the game; it temporarily suspends printing services, search indexing, and visual themes, freeing up to 15% more resources than Microsoft's native mode.

02.Game Mode vs Xbox Game Bar
Don't confuse the two!
Game Mode
ENABLE. It's an internal kernel priority setting. Lightweight and efficient.
Xbox Game Bar
DISABLE. This is the overlay (Win+G) that records clips and chat. It consumes VRAM and causes stuttering. Only keep it on if you actually use Xbox chat or clips.
03.Streamers and OBS: The Danger
If you stream, Game Mode can be a villain. Since it gives 100% GPU priority to the game, it might leave OBS with "nothing," causing the stream to lag (dropped frames) even if the game is running smoothly for you.
- If the stream lags: DISABLE Game Mode. And run OBS as Administrator (this balances the priority).
- If you only play games: ENABLE.

Hardware-Accelerated GPU Scheduling
Right below the Game Mode button is "Hardware-accelerated GPU scheduling." It offloads VRAM management from the CPU to the GPU itself.
This reduces latency and is MANDATORY for using Frame Generation (DLSS 3). Enable both together for the best results.
2026 Benchmarks
In tests with Cyberpunk 2077 and CS2:
- Average FPS: 1% difference (Margin of error).
- 1% Low FPS (Micro-stutters): 8% difference in favor of Game Mode Enabled.
Conclusion: It doesn't raise the ceiling, but it lifts the floor, making the game more stable.
