Mesa 25.0 Gets A New Vulkan Layer For Limiting The Amount Of Reported vRAM
A half-year-old merge request from Igalia's Karmjit Mahil has been merged for Mesa 25.0 that is a Vulkan layer allowing for optionally limiting the amount of video memory reported to games/applications.
Primarily for testing/debugging purposes, the new "vram-report-limit" Vulkan layer allows for limiting the amount of video memory reported to an application. From there applications may alter their behavior based on seeing less vRAM than is actually there, but if they keep on allocating memory they can still go above the artificially limited cap. Karmjit Mahil worked on this Vulkan layer for wanting to explore reductions in the vRAM limit and their impact on gaming performance.
