Massive, massive slowdowns with 4870x2

[BraTTy 0]

No such problem for XP64, ATI 3870 and 4gig ram here.

Apparantly its a Vista64,ATI problem according to the topics you linked.

8.54 Drivers are newer. What you posted is 8.53.

Also, I have to disable Cat AI for ArmA to work properly. If it's enabled, I would be inconsistent walking/driving speeds.

look at compilation date of the package ...

also don't be fooled by numbers as they don't reflect differences between various beta/OEM builds ...

Well,what about using SSD drive(32Gb)for arma?Would it reduce stutter considerably?

[Väinämöinen 0]

Fastest SSD drive at the moment is OCZ SSD Core 2.

Capacities of 32GB and 64GB and premier speeds of 100MB/s read and 80MB/s write.

So its not that fast...almost the same as running Raptors on RAID-0. Stuttering will be there.

OCZ SSD Core 2 read 143mb/s access under 0.35ms,OCZ SSD Core 2v2 read 170 mb/s access unde 0.2-0.3ms.Doesn't access be more important in loading textures?

no point to buy SSD until intel introduce his SSD for masses

[Väinämöinen 0]

Both are important, but reading rate is what matters. SSD is still too slow but its totally quiet to operate. Only reason to buy one.

slow?

Model X25-E 32/64GB size and 240 MB/s 170 MB R/W

take in mind memory drive push quite CPU usage and bus IO while SSD could utilize good I/O SATA controllers (esp real hw raid ones)

You can't get Intel X25-E now can you?

In the future...

so best to hold off on buying a 2 grand machine with dual 4870x2 cards then huh? cos arma is 1 of main games i intend to play on it?

true, but soon ....

also there are lil slower but interesting so so SSDs

Yup, in fact, you may just want to buy a machine equipped with a single 4870 (single GPU model). ArmA has never scaled well with Dual-GPU setups, and I somehow doubt it ever will. The same can be said of a lot of games.

I'm with you on this, I tried SLI for two series of graphics cards, and found it a hopeless waste of money. When i counted up the costs it was much cheaper for me to put the money on a second card aside, and simply buy a newer video card when such one came out.

YMMV however...

thanks guys. but maybe ill still benefit from other games.. ill have to have a looksy, but thanks for advice

I disagree.

Arma runs great on my 9800GX2 with all settings maxxed except AA(medium) and view distance(3500). On sahrani fps stays locked at my refresh rate of 60, except in a few forests.

Every game Ive tried on this card runs great without issues(havent really tried that many though).

Please state what resolution you're running.

I get 80 fps at 800x600.

At 1600x1200, I average 30+fps.

That wasnt what I was saying, if you were somehow able to disable the second GPU and play ArmA, you'd find that the difference is not relative to the fact that you theoretically only have half the GPU power.
