Hitching in games 256mb vs. 512mb v-ram..

[GPUCommando]

I have x1800xt 256mb, and it performs pretty well at my native res. of 1680x1050... My only issue is that I find that certain games have the "hitching" or skipping effect (not FPS drop, but jerky motion) when turning on the eye candy.

Its most noticeable in HL2, Oblivion, and FEAR. HL2 is the one that does it really bad.

If I owned the 512mb version instead of the 256mb version, would this cease (theoretically speaking)??

It just feels like the GPU is able to push the game but when turning the settings up the hitching starts - possibly meaning the ram can't fill and empty the textures fast enough.

Benchmarks show FPS, but I'll sometimes see comments about the 256mb version versus the 512mb version.

Apologies for the long post, your help is appreciated.

well with a 256mb 7900 GT, i get ton of hitching in bf2:sf at 1600x1200 HQ. But with a 512mb card, the hitching goes away. So yeah 512 helps

Probably the ram yeah. Consider the x1950pro 512 if it comes out at $200.

At those resolutions, with eye candy turned on, most games will benefit from 512MB of video memory (but only on cards that can really handle 512MB, c'mon a 512MB 7600GS?!?) I know you are talking about X1800s, but some people are like "OMFG teh 7600GS 512 ROXORS!!1!1!!11!!1!!"

Turn on antialiasing and ansiotrophic filtering at really high resolutions and 512MB of VRAM is a must.

Yes - I keep seeing people mention this card. Is this out yet?? I know Newegg doesn't carry it as of right now.

I guess at resolutions above 16x12 the 512mb comes into play. Its irritating enough with 256mb to buy a whole new card due to hitching.

And no AA in FEAR just looks awful (playing the expansion at the moment).

Thanks for the replies.

The worst one i've seen was a 6200TC advertised as a 512mb card. I do not know the configuration, but I imagine its 256mb on-board + 256mb usurped from the system ram??

If that's the case, wow... just wow.
