|Bottom Line: Performance doubled/tripled in Directx mode vs. OpenGL with no visible difference in graphical quality.|
Most of us who have GTS noticed the option to choose between OpenGL & Directx, a feature that Haulin' didn't have (you could only use OpenGL). But what difference does it make?

With DirectX mode enabled, I got >55fps inside city limits in interoir view with F2 mirrors on, as well as interor view mirrors. FPS never dropped below 45 on my trip.
In openGL mode, under the same circumstances, averaged 10-15 fps with both sets of mirrors in the city, 25-30 on the highway.
In DirectX mode, I was able to achive stable >30 FPS w/ 32xcsaa on. yeah.
So what's the diffrence, shader wise? SCS claims DX is "fallback" after all...
You tell me:
So try running GTS on DirectX mode, you might see a huge performace gain. Post your results below.
