Have you tried playing with the graphics settings on the card or the OpenBVE program itself?
Yes - I have high performance settings turned on for games via the Nvidia control panel and have messed with a few settings in openBVE itself.
Yeah, all the midrange to higher end graphics cards for some reason have a glitch with openBVE. Since michelle is gone and its been more than a full calendar year since openBVE was updated, this problem may never be fixed.
The most you can really do is download the most up to date drivers.

If it doesn't work, unfortunately you will be stuck with the same problem as me. Crap performance on a good PC.
Wow that is actually kinda unfortunate. Although my focus of building this rig is mainly for playing the graphic intensive higher-end games such as GTA IV with HD ENB settings, I still need some good exterior views for the continued extensive preview of the (R). I guess I gotta do some network drives, developing the (R) on my new desktop and beta testing on my laptop.
I'll see if I can mess with openBVE source code since I am a game developer for the mobile app markets. I should be able to pick up the language if I haven't already learned it. Should be C++. Haven't checked or downloaded it yet.
