I came across a weird problem in Crossover XI. Game launched fine including startup videos. Once I go into the game, the environment, buildings etc. are fully drawn, tanks and other models are invisible, although they are present in the scene. You can hear the audio and see slight animations where they are supposed to be. I had faced this exact same problem for The Witcher in CXG 10 (I could only see eyeballs and a mouth hanging in the air moving, it was freaky), but it went away when I used the UseGLSL registry key. Unfortunately this didn't help for RA3. This was with a completely fresh Steam bottle.
We're rebels. We're misfits. But mostly, we're software liberators. And we're very, very good at what we do. We have to be. Lots of developers work with open source, but only a tiny fraction of those are good enough to get software that was designed for one platform to work on another one. We invented CrossOver software - a unique approach to cross-platform compatibility that does not require dual-boot or another OS license. We launched PortJump to help app and game developers broaden their market beyond Windows® users. And we launched ExecMode to help organizations solve really ugly technical challenges.
