Winlogo.png Test configuration on Windows:

PCSX2 version: 0.9.9 r4878
Graphics by GSDX: r4873
Sound by SPU2-X: r4872
Pad plugin is LilyPad: r4484
BIOS version: USA v2.00


  • This game requires a ton of personal tinkering to get it to run decent.

Hack comments: Hacks: EE CycleRate (3), INTC, Wait Idle Loop, mVU flag hack.

  • 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.

Linlogo.png Test configuration on Linux:

PCSX2 version: 1.0.0
Graphics by GSdx: 0.1.16
Sound by SPU2-X: 2.0.0
BIOS version: USA 2.00

Comments: Stock settings, just the GS had to be switched to GSdx. Only problem is that in a race it is too slow (20-30 fps) and the game doesn't work with frame skipping; with hardware video acceleration enabled in GSdx, it is twice as slow. The problem seems to be the CPU. System: Core i3-2100 3.1 GHz dual core+HT, Nvidia 8800GT with proprietary 295.40 driver, Kubuntu 12.04 64 bit.

GPU: nVidia GeForce 260GTX


  • 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.
  • In Gsdx config change the interlacing mode to Bob tff to stabilize the image.

Known issues:


Crashes pretty often. Happens because of spikes in VRam use.

  • 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.
  • 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.
  • 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

  • Solution: Set VU Clamping Mode to Extra to fix.

Garbage all over screen in races

Happens when using color/brightness options other than 0.

  • Solution: To fix the super broken graphics and crashing during races set the Brightness to 0 in options.
  • Solution 2: In Ntsc version , change the display in game config to Normal, then you can set the brightness to 5 whithout the broken graphics, and get a clearer picture.

Demo races not working

Demonstrations return back to menu as soon as they start.

  • Solution: Only work with EE clamping set to full.

Broken Photos

Photos are all messy. Solution: Unknown.
