GFX.log not created. Help!

[ShadowBSE2]

Hello folks,

as so many others I also have the problem of the game looking incredibly on Extreme, although I've got a pretty potent machine. Specs are i5-3570K on 4,5 Ghz, 8 GB of fast DDR3 RAM, OCed GTX 670 4GB VRAM.
Now the first problem is that the game says that I only have 3 Gigs of VRAM, which is simply not correct... And my second problem is that I can't even see if the game downscales some (even if I ticked the override button) as my gfx.log seems to be missing. I tried locating it under ...\AppData\Roaming\The Creative Assembly\Rome2\logs. But there's no gfx.log to be seen, only event_metrics.xml and modified.log.

I played a campaign and several historical battles so that can't be the problem... Does anyone know how to get that logfile and/or fix the crappy graphics?
