ArmA2 / OA (low) performance issues

[BOTA:49]

I usually have a 6970, but right now that's on hiatus, so I picked up a GTX 570 to replace it for the time being. So far in every other game my 6970 flat out beats the GTX 570 except ArmA 2 CO. In ArmA the GTX 570 stays consistent with the frame rates, so even in the middle of Zargabad on a relatively heavy mission I still manage about 40fps or higher with very little dipping. Even worse is that with the 570 I can max out the game with everything on very high (AA on Normal, PP on Low) with a view distance of 4000, while the 6970 had the same settings except Objects and Terrain were on High instead, but as soon as I would move my head and the blur would kick in my FPS would drop and the game would stutter, as if it was loading everything in sight. It did this regardless of settings though, which was very irritating. I doubt it's a problem with the card seeing as the 6970 absolutely destroyed the GTX 570 in every other game I've tried.

is the 6970 ATI? and the GTX 570 AMD I think they are if so wonder if this is why?.

My ATI 4890 seems to run fast as hell in all me games even latest ones but ARMA as per usual still eats me system for dinner .

Thanks for the advice, I see that unless I get that time machine working I won't be able to run this at a steady 50-60 FPS, but not dipping below 30 or so would be good. I have some sort of OCD thing where lower FPS messing up weapons rate of fire drives me crazy.

ATI's counterpart to the GTX-500 series is the 6000 series correct? What's in the 200-300$ range? Also, are Nvidia cards are still running ArmA better than ATI/AMD?

My primary case fan died so I replaced it with a newer, better one. That plus the oversized copper heatsink on my CPU means I ought to try to find a higher overclock setting that won't give me any trouble.

I'm due for a new HDD, my current 10k RPM drive is almost full. Would either a 15k RPM HDD or a SDD provide a significant benefit for ArmA and other games?

I haven't installed or used a SDD before, is there anything special I should know about them? (besides for the fact that they're damn costly)

I can confirm this behavior with the 6950. I don't have a Nvidia GPU but it really does stutter and Arma seems to be [more] optimized for Nvidia.
I hope that this could be fixed in future versions. Especially since the usage of PhysX will most likely push Arma 3 even more towards a Nvidia centric universe.

SSDs are the better choice because they are in most cases much faster and have lower response times.

I was foolish and bought a hexacore 2.6ghz, rather than a more capable quadcore. I'm very limited in my overall fps in any missions it seems, especially campaigns. At a glance, is it safe to say this is due to CPU bottleneck? Overclocking isnt really feasible due to the motherboard's restrictions. I'm going to attempt to upgrade the PSU today to an 800 watt model, which will be the first step in any future hardware improvements for this computer.

What's the video card on that? I didn't see that listed on there.

Also, 2.6 ghz is fairly low for this game. Maybe try getting at least 3 ghz overclock. Also make sure that you have cpuCount set to 6 to take full advantage of your hexacore.

The card is an ATI 5750. Runs up to about 70-ish under load in ArmA2.

Don't bother with the PSU (unless there's something wrong with it). Save your pennies for a faster CPU. In fact a decent PSU will prolly cost almost as much as a fast (<3.2Ghz) CPU.

What power supply do you have?

Make and wattage please.

Also, the 5750 is a low-mid range card. I would upgrade/overclock your CPU first, but you're going to have to upgrade your GPU if you want good performance at high settings.
