Played until the Last mission, no gameplay bugs at all. The only graphic bugs were: Depth problems with the hud, massive slowdown (20fps) during big explotions (like the Death star one and the ATST one in the Endor mission) and darkened lightsaber/hud on some stages.
Im using the same Phenom II x6 at 3.3ghz emulating with 50mhz.
Also, if someone is interested, I didnt saw any performance drops when adding the resolutions or FSAA samples. It doesnt seems to be using my vga that much (As I said, its a HD5750 with 1GB DDR5 Vram).
Back to Daytona 2 PE: I have seen some slowdown on specifiq turns on the advanced cirquit. I did a few runs and it slowed down to about 20fps in the same exact part and then it continued fullspeed. Not sure why though.
PS: I'll be doing a few Scud Race benchs-runs in a while.
