My system specifications are as follows:
2.8Ghz Pentium D processor . 1.5Gb RAM and just 80Gb of Disk space
Maximum of 100MB of graphics support, Windows XP-SP-2.
In case of MSTS, the default trains run smoothly by which I technically mean I get a descent FPS of 12.
The problem is with the addons which I have added. This leads to FPS= 2 or 1. What should I change?
