Lone3wolf: Aside from about 30 seconds, to 1 minute of speedy, normal play, the whole thing looked like my characters were trying to run under water. Even on LOW and OFF settings. I have no idea what happened during that almost-minute to make it normal, but god dayamn, it was frustrating....
Goatbrush: What sort of specs is that performance on? I'm a bit concerned because my machine is ~5 years old now and sometimes it shows.
2005/6-ish machine myself...
P4 3.06GHz that HyperThread's (badly) a second core.
2GB dual-channel PC3200 RAM
ATI Radeon Sapphire HD3450 512MB GPU.
TBH, there's absolutely no difference in performance that I can see between low/off and high/on at any and all setting combinations...
I did get a few more (VERY brief) periods - a few seconds a time - of my character running at a somewhat normal pace.
It does seem to slow down more when I'm destroying scenery/props, etc.
I'm guessing it would probably work much better on a true dual-core system, and maybe a slightly better GPU. It's playable, if damned slow, on mine...just don't expect to be much use in multi-play co-op games.
