Hello, i'm having some difficulties running this game the way i'd like to run it, i tried alot of different settings but i cant seem to get one that actually working the way i want it to work. Maybe i should try other gpu's but for now i wanna try this one

First up, my specs.
AMD64 3500+
GeForce 7800 GT 256Mb PCI-e
1gb RAM
I am using home made .iso files made and run with Alcohol120% since running from my hdd is much faster then having the cd in my drive.
The best and fastests performance i had thus far is when i had almost all settings on max using industrians settings, but still i'm having some probs.
The battles seem really slow as if its too much to load, and the sound slows down aswell, yet fps keeps @ 40 or something yet i read that people here have 180 therefor something must be wrong.
Second during the battles there is a flickering in the lower part of the screen, white/black/white/black etc. I think i read somewhere how to fix this, but cant find it anymore
Then the third problem so far and that is the animation of the characters, they keep changing shape. from slim arm to fat arm, from big shoulders to slow shoulders, i dont think that this is normal, therefor it must be wrong.
I hope someone can give me some pointers on how to change this and in mean time i'll keep looking for settings on simular pc's as mine
