If that's the sort of response I can expect, I'm not going to say what processor I have...

Actually the best processor in this case would probably be a Intel core i5 680 or something similar as TPT does not take advantage of increased core count and the only reason why a i7 920 would do better I can see is the higher amount of cache but the massive clock advantage that the 680 has will give it the upper hand.

It would seem that I'm stuck with a (comparatively) archaic single-core, hyperthreaded, 3.00GHz, Intel Pentium 4. On a good day, PT runs at 36 fps. Most of the time it runs at around 10-25 fps.

EDIT: Am currently (right now) running about 11-16 fps.

My Pentium 4 541 @ 3520MHz runs PT at 56FPS using Windows XP 32bit. Increasing the clock any further did not improve the performance but that's NetBurst...

O_O Lucky! It looks like my luck just got better though: now it's running at about 30-45 fps. This is right after it randomly decided to crash. Mabey it should decide to crash more often!

With a processor that old I doubt your graphics card even supports OpenCL.

I have no clue, but you're probably right. It does support OpenGL though!

Hmm... I use my s**ty laptop for the pt (32 bit, 2gb RAM and 1.6 GHz processor) and it runs the PT at about 45-60 fps (normally 50). I dont think (seriously doubt) I have any dedicated graphics and yet this FPS seems to be running at reasonably high rate...

I remember one of the early multithread builds by Simon, it was fun watching water just stopping in the middle of the screen for no reason. After a few updates the multithreaded build seemed to work fine, were there issues I didn't know about?
