Hacks and Performance

  • MTVU may increase speed in quad cores, in dual-cores it increases depending on the race but may cause slowdown in others.
  • Other hacks cause crashes or game won't boot., *This game requires a ton of personal tinkering to get it to run decent., *This game has very, VERY high requirements. Don't expect a smooth or stable game. Heavy slowdown often. Mostly depends on track, lights and the amount of cars on screen.
  • "Allow 8-bit textures" in GSdx may help with speed a bit more and maybe reduce the Vram slowdowns.


Known Issues

Crash

  • Status: Active
  • Type: Major
  • Description: Crashes pretty often. Happens because of spikes in VRam use.
  • Workaround:
  1. If you get lots of crashes during license tests use lower internal resolution in GSdx or use ZeroGS or ZZOgl, expect much slower speeds from using the last two.
  2. In GSDX HW AA causes the game to crash alot so set it to 0, running the game with native res seems to help as well.
  3. Additionally in Windows XP even in native resolution you may get instant crashes when starting races if you don't have enough VRam, using a custom resolution lower than 512x512 seems to help.

First letter missing in menus

  • Type: Note (not an issue)
  • Description: First letter missing in menus
  • Workaround: Set VU Clamping Mode to Extra to fix.

Garbage all over screen in races

  • Status: Active
  • Type: Serious
  • Description: Happens when using color/brightness options other than 0.
  • Workaround:
  1. To fix the super broken graphics and crashing during races set the Brightness to 0 in options.
  2. In Ntsc version , change the display in game config to Normal, then you can set the brightness to 5 without the broken graphics, and get a clearer picture.

Demo races not working

  • Type: Note (not an issue)
  • Description: Demonstrations return back to menu as soon as they start.
  • Workaround: Only work with EE clamping set to full.

Broken Photos

  • Status: Active
  • Type: Serious
  • Description: Photos are all messy
  • Workaround: Switch to software mode while moving the cameras, then switch back to hardware when you take the picture.

Shaky Image

  • Type: Note (not an issue)
  • Description: In-game the "screen" is shaking.
  • Workaround: In Gsdx config change the interlacing mode to Bob tff to stabilize the image.
