This gives me a screen about A4 sized in the middle of my monitor, just about big enough to be meaningful, and I can run the Autumn Leaves Scenario on the Paddington - Oxford line at about 15/16fps to 19/20fps with a little bit of stuttering with RW3 on. My F3 clock is running more or less to time (about 9.7 game seconds to 10 real seconds).
However, when I try to run routes I have either built or uploaded it all goes a bit squiffy, as follows:
This is the "Wansbeck Sulzer" scenario on the Blyth and Tyne. The distorted image blocking the cab view is only there with RW3 on, in legacy mode (RW3 off) the view is unobstructed:

My class 47 seems to have become a helicopter! This time this corruption occurs both the RW3 on and in legacy mode. The identical Class parked in the distance doesn't have rotor blades!!

In my Sand Hutton Light Railway, I seem to have a shadowy stripe along one side of the ballast to the narrow gauge track. This appears on either side and hence bears no relationship to the location of the sun. Note that it doesn't happen to the standard gauge track! This only occurs in RW3 on and looks OK in legacy mode.

Note the yellow washed out colour of the NE Region station running in board. This only occurs with RW3 off (ie in legacy mode) with RW3 on, the colour is a correct orange.

Can anyone explain these effects and can they be fixed. It strikes me that some faults occur in legacy mode only, some in RW3 mode only and some in both. I haven't really explored much more and who knows whatelse I will find. It seems that these anomalies only occur in routes created by other than RS although I haven't got much faith in any of this now.
