Kernel patches merged for Linux 7.3 aim to lessen the performance drop when games exceed available VRAM.
For engineers building graphics-heavy applications, VRAM exhaustion typically causes severe frame rate drops and instability. These patches address the underlying memory management to keep performance more stable when overcommit happens, which is relevant for game developers and GPU driver work.

Kernel patches for VRAM management are merged upstream and queued for Linux 7.3.
Running out of VRAM forces eviction to CPU RAM, with PCIe bandwidth capping maximum data transfer per frame.
PCIe fetches have roughly 7.3x the latency of an Infinity Cache hit and 4.6x that of VRAM.
