Priority: medium Bug ID: 72575 Assignee: dri-devel@lists.freedesktop.org Summary: Several games are unable to detect VRAM size Severity: normal Classification: Unclassified OS: Linux (All) Reporter: b.bellec@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa

I have a AMD CYPRESS (Radeon HD5870) with 1 Go VRAM but several games (Serious Sam 3, Enemy Territory: QUAKE Wars, Unigine Benchmarks/Oil Rush) are unable do detect the correct VRAM size.

System: Fedora 19 x86-64 kernel 3.11.10-200.fc19.x86_64 libdrm 2.4.50-1.fc19 mesa 10.1.0-devel (git-1e71493)

I had this issue already since a long time (detected in ETQW with a RV770/HD4850) but I was thinking it was a ETQW game bug. Now that there is more Linux video game, I see that it's not specific to one game.

Here are differents outputs:
