fps for 4xaa same as no aa = cpu bound?

would it be a safe bet to say that if i get the same fps with 4xaa as i do without aa then that means i am most likely cpu bound?

i'm currently running a 2500+ w/ 9800pro and am considering upgrading to an amd64 based system if it'll make a significant difference

edit: i should've mentioned that the game i'm playing is morrowind @ 1600x1200
 
If you change your in game resolution and texture quality to very high and then extremely crap, and don't see much fps difference, then you're CPU bound.
 
But, if the speed is 'fast enough' in both cases....does it matter if you are CPU bound or not?

The thing about a bottleneck is that it's only a problem when the system isn't running as fast as you want. EVERY system ALWAYS has some bottleneck, the question is just 'does it run fast enough, or not?'.

(EDIT: 'some college town in Oregon'? Bend? Salem? Eugene?)
 
thing is that the performance isn't fast enough, sometimes my frame rate drops around 10-12 for extended periods of time (especially running around the snowy wastelands of bloodmoon in a blizzard). i suppose i could turn the settings down and see if that pans out.

i found a nifty article that shows some cpu scaling in games:

here

since i try to stay at 1600x1200 it doesn't look like cpu upgrades would help much, as in most cases their tests showed that the performance differences between a 2500+ and the a64 3400+ weren't very significant on the 9800xt card. it looks like it would be better to wait another generation or two of vid cards before a cpu upgrade would have a major impact.

the college town is McMinnville, about halfway between portland and salem towards the coast. location should really say Bosnia right now but i haven't gotten around to changing it
 
ok now i'm not so sure about anything anymore since i dropped the resolution and still got around the same framerates. went from 1600x1200 to 1024x768 and still get 15~25 fps in balmora
 
Devilpup,

It's not your CPU nor your graphic card. The morrowind engine has the known bug.
 
The Morrowind engine is a pig. Loved that game though... I played through it on a dual P3 1.0 w/ a Parhelia. That was bizzare... the only way I could get my FPS to drop was to enable 4x AA (which on a Parhelia renders everything at 4x res and then scales it to the screen... really slow) and turn the res up past 1024x768. I was running it at 2048x1536 with 16x AA and 2x AF (most a Parhelia does...) and got roughly the same FPS I got in 640x480. I dropped it to 1600x1200 after a little while though because text was too hard to read at 2048x1536. Sure looked pretty though... the jaggies were completely gone except where the FAA algorithm missed an edge, and at 1600x1200 I didn't really notice them.
Bug or not, I think I was probably CPU bound running Morrowind.
