I had a lot of trouble getting this game running on my Alienware M17x laptop so I'll post the configuration I used in case it helps anyone else. I'm not sure if it will be the same on other optimus based laptops. The system is Windows 7 64-bit, DirectX 11, GTX 675M with driver version 335.23.

In nVidea Control Panel select
- Integrated Intel CPU

In program compatibility settings:
- Compatibility Mode = Windows 95
- Run in 256 Colours
- Run in 640x480 Screen Resolution
- Disable display scaling on high DPI settings
- Run this program as administrator

In program folder:
- Delete redline.cfg (it will create a fresh one)
- Leave all graphical settings at default

This does mean the game will only be running at 640x480 but any deviation from the above resulted in a CTD on this system (and I tried a lot of combinations!). I've played for about 1 hour, created saves, quit the game and reloaded from where I left off without problems so far.

It's strange that it was so picky because the demo made at the time of the games release works fine on this machine without any fiddling.

seems like it just doesn't work on any modern nvidia card, I tried to run it on 3 different PCs, and it doesn't work.

It plays just fine on my Asus win7 laptop with Nvidia gtx 660 .

Same thing here, plays fine on my Nvidia GT 740m. Had to force the system to use the NVidia card though, it defaulted to using the Intel 4000 graphics, which caused severe graphics glitching.

For some reason the key config dialog has a lot of lag on the mouse and keyboard, but the game itself seems to run smoothly enough, if a bit skittish, I'm putting that down to the engine though.

I just tried to run this on my GTX 1080 and it gave me a blue screen. Ah well atleast it was on sale.
