Too little too late some may say, but Colonial Marines is getting a texture update some time 'next week'...maybe. And not just visuals either. The update will include a mouse smoothing option, as well as all the fixes the console iteration has already received. Better yet, it's just in time for me to get my computer back and finally play it, so check back and I'll give you my thoughts. Until then, flameshield activated and comments below.

"This update contains the changes that were in the recent update for the Xbox 360 and PlayStation 3 versions, along with some additional changes that will be part of future updates for the Xbox 360 and PlayStation 3. This update also includes several PC-specific changes, notably: improved texture resolution, various visual improvements, the addition of a mouse smoothing option, and some fixes for PC-only crashes. As this update is rather large, those players with limited or bandwidth-capped access may want modify their auto-update settings by right-clicking Aliens: Colonial Marines in their Steam Library, choosing Properties and selecting the Updates tab. Update notes will be posted as they become available."
