Valve engineer Natalie Vock has submitted patches to the Linux graphics driver stack that change how the kernel allocates VRAM on 8GB GPUs. The fix prevents background processes from evicting foreground application data from VRAM — a problem that has caused stuttering in games and, for local AI users, unexpected model layer eviction during inference. What Happened Prior to these patches, the Linux memory manager treated all VRAM allocations equally: any background process could cause the OS to evict data from VRAM to system RAM, regardless of whether a foreground application was actively using it. This meant that running a browser, a code editor, or any background process alongside a local inference server could silently push model layers out of VRAM and into slower system memory, degrading inference throughput without any visible warning. Vock's patches introduce VRAM prioritisation lo…
