Well 8 hours in, at The Hollows, playing on Apocalyptic difficulty(still to easy) the framerate has gotten better. That may be because I'm mostly indoors though, at or near 60 with vsync on indoors for the most part, drops to 40's in really heavy combat. Quite a bit lower outdoors. I wish I could just lock the framerate at 30, less fluctuations. The game really should not be dipping below 30fps with the recommended specs it has though. There seems to be a memory leak in the game, after a couple of hours, it was stuttering like mad. Hopefully they end up patching the game, there is a lot of major bugs listed in the readme file.
With all the complaining about performance, that I'm gonna do, out of the way, the game has so far been a blast and everything I had hoped it would be. I had a good laugh when a certain voice sounded awful familiar, that turned out to be correct. Amusing how close it is to the other character he plays. The only gameplay issues that is, not so much bad, but disappointing is the "challenge rooms" content filler, don't care for those. Also the manual aiming for boomarang is awful slow, I adjusted the sensitiviy but that only makes the cursor itself move faster, not actual turning. Switching between locked on targets isn't great either, but that is easily worked around. Besides all of that, everything has been great.
System specs are
AMD Athlon 64 X2 Dual Core 6400+ 3.2Ghz
Memory 4.00 GB
NVIDIA GeForce GTX 460
Win7 64bit
I was gonna upgrade to a AMD Phenom II X4 945 3.0GHz this month but emergency vet bills got in the way. Hopefully by the end of the year now, then start saving for those octal-core sandy bridge cpus coming out later next year, or whatever they are heh.
