Hi, while trying to fix the bug I posted a few days ago, the game's developer pointed out on request that the ingame shader issues are not related to the graphics card detection but more likely to a failing shader compilation.
They are using d3d9_33.dll for development and recommended to try with this version. I've thus removed all other versions of the library and also deleted the game's cached shaders. The game now crashes on startup with the following error: fixme:d3d_surface:flush_to_framebuffer_drawpixels >>>>>>>>>>>>>>>>> GL_INVALID_VALUE (0x501) from glDrawPixels @ surface.c / 1061 If I use d3d9_31.dll instead, the shaders are compiled and the game starts but the water is again looking like a low-end fallback. Any ideas on this? Regards, -- Markus
