VRAM usage has become an increasingly unavoidable issue in games as they grow more graphically intensive over time. Pushing the visual fidelity requires more assets to be stored in VRAM, which makes it harder for cards with 8GB (or less) memory to run games smoothly. For Linux at least, Natalie Vock has just proposed a new solution that alleviates this issue, providing a notable performance boost for games by optimizing VRAM usage.
Vock is part of Valve's Linux graphics driver team; she's developed new kernel patches and two specific utilities to address the VRAM usage issue. These fixes basically talk to the OS and let it know that the game currently running in the foreground gets to call dibs on the VRAM. If the VRAM starts to fill up, any VRAM consumed by background tasks needs to spill over into system RAM before the game does.
