Supported Video cards

MSI GTX 970 4G Gaming
Intel HD 4000 - lowest
Intel HD 4600 - medium

Be careful about Intel HD graphics cards, even the HD 4000 does not work when very old drivers are installed.

We tested the game with:
Nvidia Geforce GT 120
Nvidia Geforce GTS 250
Nvidia Geforce GTX 470
Nvidia Geforce GTX 560
Nvidia Geforce GTX 580
Nvidia Geforce GTX 675MX
Amd Radeon 5700 Series
Amd Radeon 6700 Series
Amd Radeon 7700 Series

Most problems occur with low budget cards: Especially Intel has bad OpenGL support when it comes to those cards (in other words: the drivers have bugs concerning OpenGL, preventing the game from running correctly). The situation is getting more complicated when you have a laptop, in several cases you have to use custom drivers offered by the laptop manufacturer. Unfortunately they don't always keep their drivers up to date, so it's possible that the graphics card vendor (e.g. Intel) has already fixed the drivers, but the laptop manufacturer still only offers the faulty driver version.
So also be careful about this list! When only a faulty driver is available for your card, you will still run into trouble.
Least problems occur with Nvidia cards btw, they have the best OpenGL support so far (in terms of driver issues).

Amd Radeon 7800 Series works on all settings fine too.

ASUS Radeon R9 290X works like a charm on all settings maxed

Asus GTX 750 Ti Maxed works like a charm. No issues unless you wanna run dual video cards.. this card doesn't have sli being a Ti version. Just a heads up

Just registered to add my own cards.

Geforce GTX 560 1GB - works
AMD Radeon 7640G (mobile / laptop) 512MB - works

Despite the system requirements stating 1GB VRAM needed, the laptop runs the game fine. So is the VRAM requirement wrong, or is the VRAM requirement dedicated + shared?

amd radeon hd 6970 2G works ok
i5-2500
16 gig ram
ultra high res
vieuw and object dist. medium
40-60 fps
