Proven fixes for FPS drops, stuttering, and performance issues.
Disable Hardware Acceleration in Apps
Many background apps (Discord, Chrome, Spotify, Steam, etc.) use Hardware Acceleration, offloading rendering to your GPU. While this can make apps smoother, it can compete with your game for GPU resources, cause FPS drops and stutters, or trigger overlay/driver issues. Disabling hardware acceleration in non-essential apps can help keep your GPU focused on the game, improving stability.
Disable CSM in BIOS
CSM (Compatibility Support Module) is a BIOS/UEFI feature that enables legacy boot support for older operating systems and hardware. On modern PCs, keeping CSM enabled can sometimes interfere with full UEFI mode features and cause minor stability or performance issues. Disabling CSM ensures the system runs in pure UEFI mode, improves compatibility with modern features like Secure Boot, and reduces legacy boot overhead.
Clear Standby Memory List
Windows uses standby memory to cache data it thinks you might need again soon. On some systems (especially with 8-16 GB RAM) Windows can let the standby list grow too large and only clear it when absolutely necessary. When that happens during a game, Windows may suddenly free a big chunk of memory, causing FPS stuttering, micro-freezes, hitching, and frametime spikes. ISLC automatically monitors RAM and clears the standby list when free memory gets too low.
Disable Memory Compression
Windows uses Memory Compression to fit more data into RAM by compressing it. While this can reduce paging to disk, on some systems the extra compression/decompression work can cause micro-stutters or inconsistent frame pacing—especially in games or heavy multitasking. Disabling it may help reduce micro-stutters, improve frame pacing consistency under load, and lower CPU spikes caused by compression.
