Shimmering/tesselating graphics

On certain routes and certain scnery i get a shimmering/tesselating effect and its quite annoying. Does anyone else have this problem and have a solution for it?

I think increasing the level of anisotropic filtering and/or your antialiasing would help. If your video card is controlling these items(via NVIDA Inspector if you have an NVIDIA card), I would turn that feature off (choose Application-controlled) and have the game determine these levels.

having SSAA 1x2 in game settings helps a lot with this, on ATI cards anyway...

also a little negative LOD in the graphics driver options helps too.

Yep.
I've been bored and doing some experimenting with Nvidia settings today and what I've found is that the in game settings override the Nvidia Control Panel, even if you select "Override Any Application Setting" for the antialiasing.

I would select the override and set the setting high in the control panel, but set the in game setting to off and get terrible jaggies.
I could do the opposite; IE select override, then turn on the in game antialiasing, but turn off the control panel antialiasing and the jaggies get minimised.
I'd like to know why the Nvidia controls can't override the in game controls.

I always restarted everything between settings changes to make sure the PC, Graphics Card and game started from scratch.

Hmmmmm...

For me, this is the single most annoying aspect to Railworks. No matter what combination of RW/NVidia settings that I try, the shimmering continues. Some routes seem to be worse than others, and some objects seem to act differently than others. For me, the Scottish ECML shows some of the worst shimmering. I love the route, but it can get very annoying. During daylight hours, the red/white checkerboard 'Warning - Limited clearance' signs that line the Tay Rail Bridge shimmer whether TSX is on or off. As the sun sets, however, the shimmering disappears. When TSX is on, the reverse side of speed limit signs shimmer; turning off TSX eliminates it.

I had read that it had to do with the way textures/colors were stacked on an object, and that there wasn't much we could do about it. But I'm hoping someone comes up with a more satisfying solution.

Eric
I have found that some direct graphics card settings do override tthe internal settings particularly if you use nvidia inspector. Try this in NVI (do not use the NV Control Panel after) for global AND railworksproc32.exe
In NVI
set everything to override the internal RW settings.
Set FXAA Indicator to "ON"
Set Antialiasing setting to 8xSQ
Set Antialiasing - Transparency multisampling - Enabled
Set Antialiasing - Transparency supersampling to 4 x or 8 x Sparse grid supersampling (SGSS)
Set Show PhysX visual Indicator to "ON"
Set Frame Rate Limiter to some non-standard figure say 34
Set anisotropic filtering to 16
Save changes

Open TS2012, TSX "ON" and the settings panel set SSAA to 2 x 2 or similar.
Now run TS2012 and if you are running FRAPS you should see the frame counter limited to 34 on loading and when the sim opens you should get 4 small screens showing the PhysX Indicator to "cpu" and FXAA as "OFF" or "ON".
This just shows that some settings do override the internal settings, but unfortunately these settings do not eliminate the shimmering etc with TSX on.

The only improvement I have seen is to turn OFF TSX and use the above settings (without indicators) and use SGSS x 2 (not x4 or x 8). In the settings use the highest MSAA setting and AF to Bilinear and you get much much less shimmering and good frame rates, but you lose all the TSX effects.

So Eric it would appear that you can't improve the TSX settings via direct graphics card settings but it may have some impact when not using TSX. And again this may vary from system to system.
