Large instances appear to have a VRAM leak with the 9070xt as I've found during the recent Furality Soma. This was tested with the most recent 25.6.1 driver. As people logged into the instance my VRAM usage would exceed the 16GB VRAM buffer and would very quickly max out my system RAM (32GB) causing frame time issues. Rejoining the instance after people stopped joining flushed the VRAM and fixed the issue. My friend running a 6900XT in the same instance never experienced this overflow.
