Error Message

[Richard]

I read on the web site that open rails will run on any machine that currenitly runs MSTS so I figured I'd give it a try. I downloaded and unzipped the openrails.zip file without any errors. I then installed .Net 3.5 and XNA 3.1 Redistributable without receiving any errors. But when I try to start the open rails software I recive the follow error message:

Probably the video card. They did warn that they started with the MSTS minimum system specs but might leave older systems behind, and on page 9 of the SoftDocs.pdf;

"Your video card must also support Shader Model 2.0 or better. Video cards built in 2005 or later should be compatible, but please check with the manufacturer to be certain."

Quick google for pixel shader 2.0 turned up this;

Assuming that info is correct, the Ti4800 doesn't support pixel shader 2.0.

Jim, Thanks for the reply Yes this is a older machine but I figured I give it a shot

I got an "older machine", you got a fossil! Good news is you can upgrade the video card pretty cheap;

I'm assuming that Ti4800 is an AGP slot rather than PCI-Express, but even with AGP you can get Pixel Shader 2.0 or better.

Jim, It's been so long since I've played with this hardware stuff But I do believe it's a AGP card. The card fits into a green slot with a latch on the rear of the slot that contacts a tab on the rear of the video card. Thanks for the info on the cards, for the low price I just may get one to see if that improves my machines performance and allows me to try Open Rails
