I have been playing warband fine in DX9 mode since early beta - at first with a nvidia 6600GT and 1GB RAM, then with a 7900GS and 2GB. My computer is pretty old, so if the map is large or there are a huge amount of players the FPS can drop pretty low, but it works fine for native MP maps and player numbers. I suspect a factor in the problems some are having is that the linux ati drivers are generally worse relatively to windows than the nvidia ones.
I used the latest wine version up to 1.1.41, and then stayed with that until the other day, when I got around to finding and patching the bugs so 1.3.9 works: this black screen at start bug
is the main one (probably only happens with nvidia and 64 bit linux), and for a start I needed to patch this crash on start
, but strangely it dissapeared so I don't need the patch anymore; also using the latest XInput2 patch
to fix the mouse bug. I'm not using any other wine tweaks, just the default wine with no dll overrides or DirectX installs; though as detailed earlier I have in rgl_config.txt "use_secure_connection = 0" to connect to servers, "use_winmm_audio = 1" for the sound to work, and "render_buffer_size = 200"; HDR doesn't work properly, but I don't care.
