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: # dmesg |grep drm [ 1.106556] [drm] Initialized drm 1.1.0 20060810 [ 1.129686] [drm] radeon kernel modesetting enabled.
