01.Why does Roblox lag so much on Windows 11?
Roblox seems like a simple game, but it demands a lot from the **CPU** to process physics and the map in real-time. On Windows 11, the system often prioritizes updates and telemetry, leaving Roblox in the 'background'.
If you play on an older PC or Laptop, the secret is not to change computers, but rather to clean the Windows 'junk' that is preventing the processor from focusing 100% on the game.
Tip: Windowed Mode vs Fullscreen
Always use Roblox in **Fullscreen mode (Alt+Enter)**. This allows Windows to apply Fullscreen Optimizations, which drastically reduce the delay between command and action on the screen.
Don't do it Manually.

02.Removing the native FPS Limit
Many don't know, but Roblox is locked to 60 FPS by default. Using 'Unlocker' tools is safe, but you must ensure your Windows is optimized so that the CPU and GPU can deliver the new frames without interruptions.
With Voltris Optimizer, you clear the task schedules that interrupt your gameplay every millisecond.
