Narf_the_Mouse: @Henkkles: Odd, but that last line about NWN1 using only 0.7% CPU tells me your problem is probably, and unfortunately, entirely different. :(
So my solution won't work for you; or, rather, if it did, you've still got a much bigger one.
Try running CPU-z, and see if your CPU is running at around or over full speed when NWN1 is running. If it's at a downclocked speed (mine idles around 850 MHz if there's little to do) then... I don't actually know, but it would be another data point.
Hopefully someone else will know more. :/
Edit: Had another thought. Check to see if your anti-virus/malware scanner is running high at the same time? Persistently and repeatedly scanning mwmain.exe could have that result. And check for anything else using CPU at the same time in general - Might get some info out of that.
The multipliers are jumping between 8-32 simply because my full CPU utilization is around 7% when NWN is running. My virus software is Avira which shouldn't have problems like that. Like I said, my CPU is not being throttled as it's being utilized 5-7% total while I'm running NWN, which would mean that for some reason my processor can't seem to be able to allocate resources to running the NWN engine. So my solution won't work for you; or, rather, if it did, you've still got a much bigger one.

I've tried fiddling with affinity and resources but to no avail so far. My CPU is a hyper-threaded dual core, which might be the root of the issue. However my system is a Thinkpad and I don't think the OEM BIOS has a switch to enable/disable HT.
