Not sure if this actually makes any difference but I disable indexing on the drive I have Trainz installed on in Win7.
Could try adjusting the display settings in the Nvidia Control Panel? Improved things a lot here, using a GT240
Under 3d settings, use the Trainz2004 settings, it does work for any version over 2004.
My settings at present are:
Ambient occlusion = not supported
Anistropic Filtering = Application Controlled
Antialiasing - Gamma correction = On
Antialiasing - mode = Application controlled
Antialiasing - setting = Application Controlled
Antialiasing - Transparency = 2x (supersample)
CUDA - GPU's = Global (all) - only one so doubt if that makes any difference anyway
Maximum pre-rendered frames = 5
Multi-display/mixed-GPU acceleration = Single display performance mode
Power management mode = Prefer maximum performance
Texture Filtering Anistropic sample optimisation = On
Texture - filtering Negative LOD bias = Clamp
Texture Filtering - Quality = Quality
Texture Filtering - Trilinear optimization = On
Threaded optimization = global (auto)
Triple buffering = Off
Texture Filtering - Anistropic filter optimization = Off
Vertical Sync = global (use 3d applications settings)
Hello Clam1952,
Thank you for your info. I will try those settings and report if changes take place.
