Hi All,
Thanks for all the replies. I have stated going through your suggestions and will provide info on where I am up to.
So, first, are all the old ATI drivers removed - good question! How do I check? I have gone into Device Manager but it only show the current card. I also looked in Add or Remove programs but was not listed there either. If someone knows how I can check this let me know. I still have the old card so can put it back in if need be to uninstall the driver.
Second, have now turned off shadows.
Third, nVidia driver is the latest version from their website.
Forth, how do I check if the nVidia settings are on performance?
Fifth, I have direct x 11 not 9c - I have tried to find version 9c online but cannot. Does anyone have a link to this version so I can download it?
Sixth, screen resolution is the same for both.
Seventh, no screen saver is running, however, my wife does have a desktop slideshow running that changes the desktop background once every 30 minutes - should I turn this off?
Eighth, I have now used game booster to close any background programs.
Ninth, Trainz is on the trusted list for my firewall and anti virus.
Tenth, did not change the PSU as the guy at the computer shop assured me it would handle the card. It is a 550W and the card recommends at least 400W. If need be I will upgrade the PSU also.
So now to see how it runs!
The verdict, not great put playable. It now seems the route that I am having the biggest issue with is Avery-Drexel. All others are at least not freezing when I change view. Drexel is still freezing when changing views, and also when I try and save my progress. But hey, small victories!!!
Cheers, Aaron
PS just saw the thread re downloading direct x 9c! Doing it now. Will keep you all posted on how it goes.
Thanks again for all the help, it is greatly appreciated
