Read Installing MSTS on an Windows XP PC. If you're using Windows XP (really? - in 2021? 'C'mon, man!'), Once again best to stick to nVidia graphics cards. This is shown as 16.300.2511.1003, dated on the Driver properties screen (from Device Manager).' The challenge appears to be that Windows Update updates these drivers rendering MSTS unplayable. Ged Saunders over on uktrainsim writes 'The last version of the HD Series drivers available from the AMD site which enables MSTS to work under Windows 10 with an AMD HD graphics card (plus 'fix') is 16.8.3.
It appears that MSTS will install but not run on PCs fitted with standard Intel Graphics cards (theses are often embedded in the motherboard).The process is VERY similar to previous installations but I hope a few tweaks to make it easier along the way. An MSI GT 1030 SFF card has been installed and a pure/unenhanced version of Windows 10 Pro installed.
It's mostly the same as previous guides and has been tested on a 'virgin' Windows 10 pro 64-bit HP Deskpro that's recently been retired from active duty. I've decided it's time to upgrade my install guide.
