the problem is on your side. it plays just fine for me at the same speed +- with the 1888.
Post your settings first. There is a screenshot button at the botton left to help you with that
all those settings are normal. what about the plugins you use? the settings in them?
1) untick the allow 8 bit textures, its just bad for mgs3
2) use sse4.1 its faster
3) make an iso of your game with this:
http://www.imgburn.com/
4)be sure the image you will make is not mounted in any program (like daemon tools power iso or whatever)
5)use linuz iso plugin and select it inside the plugin and press ok (dont comress it or anything like this just select it)
6) press run cdvd
thats all.
my game is already on an iso, i made it from the original long time ago.. somehow i fixed the gama problem but its hell too slow..
the gama problem is this:

i will now try the rest
just follow the steps one by one exactly and you will be fine, set both clamp modes to NONE also for some speed. dont expect miracles with this game and your pc
we, thanks but no matter what i do, i just cant fix the gama problem and the game crashing after that.. but once i was lucky and the game has running without that gama thing and it didnt crash, so if i fix the gama i also fix the crash problem..
