[Bug] Severe speed degradation in Moto Racer Options Menu #60

Open unreal9010 opened 2 years ago

unreal9010 commented 2 years ago

Describe the bug Going to Options Menu in 1997 game Moto Racer causes PCem to run at about 10-20% speed (other menus and racing part of the game are usually at 100% or close). Similar thing also happens with 3-2-1 counter right before the race kicks off. Changing the CPU speed or CPU type makes little to no difference. The same issue also exists with any Socket 7 or Super Socket 7 machine that I tried. Installing patches does not help either.

To Reproduce Steps to reproduce the behavior:

  1. Launch Moto Racer
  2. Go to Options Menu
  3. See error

Expected behavior The Options Menu shall work without speed regression, just like other menus.

Interesting....doesn't happen with Voodoo 3 or Voodoo Banshee. It only happens when Voodoo 2 is present regardless of the D3D settings used in the game or even switched off. I think the bug is linked to the Grim Fandango issue I also described. A similar thing happens when I open the drop-down menu in the game Hardball 6. Again, only with Voodoo 2.
