Exact same problem. Stress/Heat-Tested video card, GPU, etc etc... My system can run far more intensive programs than KSP *and* can run earlier versions of KSP without any issues at any graphic settings/resolution. I use this system for work so it gets checked regularly for malware, viruses, etc; and whether active protection is on or off, KSP 0.90 still crashes with a Display Driver Error. Error occurs without mods; with mods like ATM, DDS, etc; with every video driver version to which I've been able to roll back. It's a bummer because this is one of the best games I've seen in a long time and I'd love to continue participating in these early stages. Same version as zero1m, but on Steam Windows 7. -- That being said, in addition to a large community of players trying to help players on these forums, it's worth mentioning I've also noted a very active Developer presence (during the Holidays no less!). So that's giving me a lot of faith that if this is indeed an issue with KSP, it will be sorted out eventually: so nice to see a Team who cares enough to stick out their necks: keep up the good work!
