Open your ET. And under "Mods" check "etpro". Does it crash? If so, then go on to the etprofolder and open your player config file. (Not sure is it "autoexec.cfg" or "/profiles/etconfig.cfg" or "<player name>.cfg". And search for "r_mode". What does it say under it?Added (07/08/2012, 12:53 PM)

Oh, if you use djuki's example, that may be the problem. It uses "r_mode -1" which means a custom resolution. And that custom resolution is determined with "r_customheight" and "r_customwidth". And djuki uses 1920x1080 resolution in his example. So if your screendoes not support full HD then that's your problem.
So try "r_mode 6", for example. If you know your screen resolution then you can put the custom one - if you want the screen to be rendered as a full-size. You can also check for "modelist" to see what are the custom resolutions.
