<pre>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:
