I had similar problem with windows 8. Went into my nvidia control panel and i chose "Use my preference emphasizing" , then slid the bar over all the way to quality. This worked for reasons beyond me. I went through most of the steps people suggested on here and nothing worked but that.
How graphic intense is a 20 year old game? This would be like solitaire not able to play.
ok guys i wont be very good at explaining this but.. mine is working as of now no more flipping.. you need to go into your BIOS and enable your CPU then save that.. may have to unplug from back of pc of your graphics card and plug it into the cpu to play dtr2..
this may or may not be relevant,i was having trouble with win 8.1 and 10.pc is a intel i3 3.4 mhz.
i got the game to run with the compatability settings but the mouse on the gear setting was like rapid fire.
i put in an old geforce graphics card and it stopped it,another thing was that i couldnt drive with any of my old setups.
I now have windows 10. Offline the game runs perfect but when going online the car jumps and jerks all over the place like its stuck halfway under the track. Ive tried everything mentioned in this thread. Anyone have any other ideas?
ps i am not going to run the game with on board graphics. No sense in having a better pc and not being able to utilize it.
