DiRT Rally Crashing Upon Launch

MadmanMitch

As stated in the title, DiRT Rally is crashing upon launch. I see the splash screen, followed immediately by the "DiRT Rally Executable is not responding." window. Contents of said window below:

As can be inferred, I've recently installed a new processor, motherboard, and RAM. The processor is overclocked to 3.7GHz and the RAM to 3200MHz. The game still crashes if I disable the over-clocks, however. Uninstalling and reinstalling the game did not help, nor did simply attempting to verify the files through Steam. One thing to note is that the game has not managed to create its documents folder, which makes me suspicious that it may be attempting to load configuration files from the Steam cloud which is making it expect different hardware than it is finding. Disabling cloud synchronisation coupled with another re-install did not help, though. I also tried running the game in administrator mode as well as trying to run it directly from the .exe rather than through Steam: still no luck. I tried creating a log file by adding "-logging" to the launch options, but no file ends up being created. Any help would be appreciated.

Same thing for me, apparently it's been an issue for people running on high core count Xeons too, they just never fixed it. 

Currently the only fix is to lower your core count to 8 either with msconfig or disable smt.

Hello, did they help you to solve your problem?

Have you tried editing the game workmap file to lower the cpu count? Try the workmap4 file first and keep changing until you max out the cpu cores. It's been awahile since I've had to edit the config files in the system folder but you basically have to point it to a lower core count file. BTW there is no 12 core file :
