AF on X1900XT ...

[Buckster]

seems to be a real performance draw on my X1900XT - is that normal ?

I run at 1900x1200 (Dell 24 inch monitor) - and 2x AA is fine - but anything above about 2xAF and I get stutters - which are really annoying.

I've noticed this in other games too.

any ideas to why AF gives this stutter/performance loss ?

AF on my previous card used to almost be for "free" - and you could use 16x regularly.

thanks, Makr.

That res needs a lot of memory, does your video card have enough, does your system

Echoing what has been said above, how much memory does your card have? Also what was your previous card?

 

[Buckster]

512MB on the X1900XT

2 gig RAM under vista

have been considering going up to 4 gig - but on checking RAM usage in FSX etc - it doesn't seem to all get used up as it is ?

 

[Buckster]

previous card was a X800XT or something

was at lower res's etc

I just remembered in the past that AA was a major headache - but AF you could almost get away with 16x most of the time

X1900XT really doesn't seem to like it at all

At 1900x1200 I'm not surprised!

And playing what exactly?

FSX ....

Bioshock etc I play on my 360

so bascially my card hasn't the b/width for this high a res ?

2900XTs are quite reasonable now ....

You could ask someone with a 8800gtx how they fair at that res and compare. Use fraps to record average fps

I thought FSX was a computer nasty game in general... maybe someone browsing this with a higher spec will give an opinion with FSX.

FS-X is a VERY demanding game.

I play FS-X with max ingame with 50% autogen/flights etc and its fine @ 1600x1200 with ingame AA and AF... about 15-30+ FPS...

X1900XTX @ 709/845....
