RW3 installed perfectly. Horseshoe Curve Add On installed and runs perfectly. No assets missing. All is well with them.
However, when I load my custom route, I keep getting lock ups and stuttering to the point that I can't even move around. I tried running my usual AI trains and they jumped and stuttered. Jerk, jerk, jerk and never smoothed out. Trying to fly from one place to another has become nearly impossible. I cleared the cache earlier today but that had no effect.
Anyone have any ideas???
I can run Horseshoe Curve with no glitches at all why, all of a sudden does my custom route go haywire???
