MBAC on Multi-core PCs

[HoTsHoT]

I have an AMD Athlon X2 which I run MBAC on, and it only gives me an average of 55 FPS.  With 2GBs of RAM and a 7800GT, this meets the requirements more than a long shot.

I was guessing how could this happen, till I forced MBAC to run on a single core, and everything sped up to what it should be. 

Now my question is, anyone having the same problem as I am?

I'm running MBAC on a Pentium D, I haven't configured anything much, and it runs fine, so I can't say I"m having your problem.

Certain games do not like multithreaded or multicore machines. I know for a fact the two older Thief games crash if you're using multicore and don't tell it to use only one.

Could just be compatibility issues.

Yeah, it's games don't don't require much should be forced to one core, otherwise it sorta confuses your pc, especially on Vista since that operating system uses resources all the time when they are not in use as a default function to "increase functionality" The same thing happend to me with The Sims 2.

i use intel core 2 duo and 2gb ram with vista ultimate and it runs well on mine o_O.. maybe clean some junks or registry?

Just installed Dual-Core Optimiser supplied by AMD and it now works beautifully on both cores. Seems that it's a core issue here.

Seems it's an AMD core issue. I have a 2-core Centrino Duo in my laptop and I've never had any problems running the game on both cores.

After reading from many sources, this stuttering is a global issue with dual-core processors and Windows XP, so whoever's running Vista will not encounter this problem.

You need to force it to run on a single core.

I had this problem before. I'd restart my computer and run MB on a dual core. It'd run on 60 FPS. Then I'll leave it on and come back a few hours later, and it'd drop to around 40 FPS. It doesn't happen if I run it on a single core. You need to do this on netplay too, or people won't like playing you. There are programs out there to automatically force programs to run on a set number of cores automatically so you don't have to Ctrl+Shift+Esc, Right Click, a, space, enter, each time (if you're running Win XP).

if you have a bad dual core that is

Your case reminds me of something I read online before. The Time Stamp Counters on each core become more and more unsynchronized, leading to further and further slowdowns. Another symptom would be your pings showing a negative value due to this very problem itself. This only happens after your PC has been running for quite long, but installing DCO fixes this.
