Playing around with Train Simulator Graphics settings on BradsPC with the following observations:

• Ambient Occlusion - Dynamic - huge hit on FPS - down to 14.
• Ambient Occlusion - High - 14 FPS.
• Ambient Occlusion - Low - still 14 FPS and I can't see any difference.
• Ambient Occlusion - Off - 32 FPS.

In summary, ambient occlusion is a huge hit on FPS for no noticeable difference.

• Anti-aliasing - FXAA + 3x2 SSAA - looks best and C69 LUL speedo works.
• Anti-aliasing - FXAA + 3x3 SSAA - not much better than 3x2, but C69 speedo does not work.
• Anti-aliasing - off. Looks very jaggard with frame rate slightly higher at 37 FPS.

In summary, FXAA + 3x2 looks as good as the higher setting, AND the speedo in C69 stock works correctly.

• Anisotrophic off - FPS = 32 - speedo not working correctly.
• Anisotrophic X8 - FPS = 32 - speedo working correctly.

In summary, Anistrophic X8 has no hit on frame rate, and the C69 speedo works correctly.

Best settings for BradsPC seem to be:

• Ambient Occlusion off.
• Anti-aliasing - FXAA + 3x2 SSAA
• Anistrophic 8X.

These setting result in an average 32 FPS on LUL Virtual District Route.
