Actually, it runs better than I'd expected on my rig, after some messing around with the vid settings ingame. Despite the multiple posts at Ubi about mid to high end systems being unplayable etc, I'm on mission 5 of the RAF campaign. With 3 kills and a few good hits too. ( you get a percentage after each mission telling you how much damage you did to each plane )
I guess trying a game, them changing a setting, then trying it again is beyond a lot or people with high end systems
Does take a few reboots to get it right, and also no matter how large your HD is, it won't matter if your o/s is on a partition with no swap space.
Biggest issue after launcher crash, is that the game won't end after exit. So you have to use 3 fingers and task manager ( shock horror!! ) to end the crappy music.
Frame rates are not at all like il2 1946, stutters happen ( use the pause button and wait em out ) but I'm guessing that if I can get 20-30fps in the merge and turnfight, land 4 times out of 5 and not be confused by the massive ( and I mean massive ) amount of keys you could use. Then this game might be quite good.
I do think that making 1 core do most of the work, then the other 1 ( or 3 ) take up the slack is a bit poor. 50 percent of your cores should be maxed out on 1 process type and the others should be doing supplimentary stuff like sound or collision detection. But I'm not a programmer so no expert.
