Which setting? I have them all set to "normal" on a 2.8ghz Athlon II x4 with 6gb memory and nVidia GTX550ti so....
And this is a new, post SP1 issue - I hadn't posted like this before because others were talking about bad "popup" which I also have, but I got so frustrated with it today (seems to vary one day to the next how bad it is).
BTW: I also use GameBooster to knockout unnecessary tasks.
That looks similar to something I've had happen, although mine seems to affect whole splines (long splines at that). N3V are looking into my case for me, so once I know what's happened, I may be able to assist you.
That happens to me literally all the time on my current layout. Don't know if It has anything to do with the quality of track as i'm using the JR track..
I try to ignore it and hope it will be fixed soon.. along with the invisible trains/bogeys.
And invisible trains, or half trains - got that one too....
Real annoying when I went to mouse on the throttle and another bug - one that makes is so that if you have the "noctrlrightclick" in trainzoptions, you leap to another consist if it happens to be BEHIND the controls in your cab - and I want to jump back before the train I was driving gets in trouble... >.<
