How to enable SLI in this game

[CodenameJack]

1. Download NVidia Inspector
2. Look for Race Room Profile
3. Add RRRE.exe into the profile.
4. Sli Bits (dx9): 0x02400205 (Race - The WTCC game (Steam version), Race - The WTCC game, Microsoft Flight Simulator 10, Dizzel, Deep Black, BlackSite: Area 51, Drakensang, The Witcher, Race 07/Race On)
5.Number of GPUs in SLi: 2
6.SLI predefined mode: SLI_PREDEFINED_MODE_FORCE_SFR

That's all.

Works fine while on track, but gives me huge flickering in the menus.

Thanks anyways for providing a solution!

[Kanard Laque]

yes

OK, found in some forum post that in order to get rid of the flickering, you need to set the game's launch options to:
-cefNoGPU -cefNoD3D11

Works perfectly now...!

Good to know, i will try those launch options too. However, the most important here is SFR, some dx9 games work
better with SFR than AFR. SFR doesn't
work in dx11 games.
