Hi
I'm on a Intel core 2 Duo 6600. It's a bit overclocked to 3.00 Ghz. 4 GB Ram and a Gforce 8800GTS (first gen). I'm running XP 64 at the moment.
Black Shark Performs very well so far. Most graphic settings in Black Shark are on High, except visibility range. A simple training mission with resolution 1650x1080 and 4x AA gives me about 30-40 fps when in cockpit. More outside. I tend to go for a tad lower resolution though, and then fps is of course a lot better both inside and outside.
In any case the engine is much improved compared to Lock On. Sometimes, you can still see micro stutters, but even that is much better. So far mostly a very smooth experience, but I haven't put heavy stress on the simulation yet, with intense and crowded missions. If you crank up resolution, all graphic options and go into a mission with rain and full overcast skies with a lot of active units, I guess most machines will take a severe hit. But that is not really a surprise.
Everyone needs to find a good compromise between looks and fps, and the mission makers need to construct missions that doesn't burn out the players cpu. In short, a very much improved experience when it comes to performance, but don't expect miracles. It is still the Lock On engine in parts.
cheers Porphy
