For those that are interested here is a post from a guy called 'Sim' over at simhq, he is an Oleg and Luthier fan this is what he posted.

At the moment, this game is unplayable without a patch. It doesn't matter if you have super-computer because it will lag even on lowest settings. The game runs in 32 bit mode only, runs only on single core CPU and uses about 1gig of ram in quick mission over sea with one other plane. I don't know what anti-epilepsy they are speaking because I'm about to have one with additional rage from being so frustrated. There are bugs - easily visible that should not have been at this stage of a game. Frame rate oddly enough shows 30-40 fps using in game counter. But my eyes sees 10 fps, if that. Patch is needed. And fast.
