--- Comment #27 from Vincas Miliūnas vincas.miliunas@gmail.com 2012-12-11 16:30:48 CST --- I tested using http://mwreplays.com/replay/4DVYFZ381463/ (version 8.1) replay with the default config, looking at the in-game FPS at 20 seconds before the start of the battle.
pre-patch with workaround = 18-19 in-game FPS pre-patch without workaround = 6-7 in-game FPS post-patch with workaround = 18-19 in-game FPS post-patch without workaround = 6 in-game FPS
The workaround is http://dl.dropbox.com/u/6901628/disable-dynamic-vertex-buffers.patch
Nothing's changed on my machine. Just to mention, my low settings config give me twice the FPS when running natively in Windows (vs WINE w/ workaround).
I am running an AMD Radeon HD 6770 w/ fglrx 12.10. glxinfo does list GL_ARB_instanced_arrays in OpenGL extensions.
