View Full Version : Psychedelic Flashing Colors!

August 10th, 2009, 12:39 PM
Occasionally, when I am working in Surveyor--- or when in my session and click to transfer to another loco, SUDDENLY, there will be brief but striking flashing of patterns and colors! The flashing will keep on until I scoot away from the loco or scenery to a plain section of the route, like a field or something. When I try to return to the loco, the flashing begins again. So far my session or route hasn't crashed, but this is very frightening. I have a 200 mile route I'm creating and this can be un-nerving. Anyone have any idea what is causing this?

Sounds like a video card fault. I had a similar problem on my old Geeforce 4 MX440 Card, but in another game (TRS04 wouldn't run at all), where it would suddenly start displaying bizarre flashing lights and artifacts.

It gradually got worse until finally, games became virtually unplayable. Thinking the video card was on the way out I replaced it with a more powerful Geeforce FX5600 (a video card I still use). When I pulled the old MX card out I discovered that the graphics processor had actually melted, possibly from overheating.

I'm not sure if this is the same problem, but in most likelihood this is a video card problem (either hardware related or a buggy video driver). Hopefully someone else will have more substantial help.

Thanks for your reply, but this is a new computer (Falcon Northwest) with a new video card. I had these same flashing occur on my old Dell computer. They normally occurred in a yard scene. A large yard with several locomotives present.
