Emulator

Well, it is well known that the more functions you add, the worse it's going to run.

But we prefer compatibility over speed.

I don't think that is really the case here XK (though I'm not sure)
it seems like nvidia cards have suffered quite badly recently, and ati cards not at
all.
for example people are getting great speeds on smg with ati cards which should be
slower than my gtx280, and yet I get worse speeds than them...but only recently.

However, until I get some way to profile opengl calls or something, I can't be sure
what the problem is...

yeah my GTX260 really fails on SMG

Sounds like a bug in NVIDIA drivers, because ATI drivers work perfectly fine except
for a memory leaking bug, but otherwise no big performance hit.

Probably comes from increased use of framebuffer objects combined with crappy OpenGL
drivers. I already eliminated usage of the OpenGL function "glCopyTexImage2D" because
NVIDIA drivers don't do it right. (ATI drivers do it fine...)

maybe sorta off topic (since it's probably not gfx-related), but there's seemingly a
bunch of memleaks currently. really should hunt them down and fix them :p

Actually yea, i'm on Gforce9800 Gt

But i have a huge slowdown for now, in the start of the game in observatory it was
50fps, now only 27-30 is left

I tried the Single Core mode and i get only 3-4fps less than DC

I have a GTX 260/216 and slowdowns too ;(

i can confirm this. TvC was running 60fps fullspeed a few revs back, now (rev 3680)
its down to 30-40 fps(nv 9600). SMG (in the observatory/room select lvl) is down to
30-40 frames, with smg hack enabled 20-30 frames.

SMG is fast once again after Nolan.Check's last commit, thanks
