Performance with ATI 4850 = NVDIA 7800GT

[flashbang151 0]

Hi, i play Arma with a ATI 4850 and the performance is just like my old Nvidia 7800GT. I tried different operating systems but its always the same. Does somebody knows a reason?

AMD X2 4200

2 GB RAM

ATI 4850

XP and Vista

Here is an example for you

System 1 E6850 with GTX 280

System 2 E8600 with 9800 GTX

System 2 runs better this game is very CPU dependant

Yes, volkov956 is correct - ArmA is very CPU dependent. However, your CPU may be bottleknecking your 4850. What speed is your CPU, what FSB does it have and how much cache does it have? Sorry, I'm not familiar with ATI processors.

Athlon 64 X2 4200+ 2.2 GHz 512 KB

I run X2 6400+, GTX 280 and 4 gigs of Corsair XMS2 800mhz, what is the bottleneck here?

Possible upgrades would be +1ghz ram, quad core processor and some SLI/Crossfire GPU solution..?

It's not just his Athlon X2 4200+ causing the bottleneck, it's the age of his platform. Even a basic Core 2 Duo platform would be a major improvement. I'm sure the HD4850 runs Arma very impressively but not on that platform.

That's one heck of a combination. I'd think that your video card is being bandwidth-starved by your platform. You'd need a much newer platform (Phenom II X4 or at least a high-clocked Core 2 Duo) to see your GTX 280 fly.

Hmm, thinking of going with this next..

AMD Phenom II X4 940 + K9A2 CF-F AMD 790X

Any better?

Thanks for your responses.

I know that my CPU is the major problem, but i thought Arma runs better with the 4850.

it does, you should be able to run with higher settings/view distances, in SP forsure, but in warefare or large AI Multiplayer stuff, the CPU will toss you down., then again only 512mbs of ram can hold your settings back too... 1g is better for this game.

And that's the problem:

Arma is not playable.

1680x1050, 2,5km viewdistance, shadow: low, AA and AF: low, shader: low, postprocessing: low.

Average FPS: 25 on Rahmadi.

Have you tried putting shadows on high? When you have a fast card and a slower CPU, it should help. Also you could put shaders on high because it shouldn't make a difference. But I would lower the viewdistance, many visible objects can make it worse for the cpu. And the objects themselves on low too. Maybe try experimenting with AA, the game could actually run better in some cases with higher AA if the cpu is slow.

You're cpu is the bottleneck here. It's the easiest thing it is for someone who is inexperienced in computer hardware to blame it on the video card or compare it to an outdated Nvidia architecture.

Pick up the Asus M4A79 Deluxe instead of that MSI board and you should see major performance improvements.

Meh, there was none available, all sold out, so i picked this MSI board for cheap 60 bucks. With 6400+ no noticeable gains even with 280GTX.

However when i added phenom in, performance gain was quite crazy, well more than 100% increase, capped to 60fps+ @ 1600x1024 with everything maxed, just amazing - even this phenom clocks 200mhz slower stock.

Oh, and clocks no probs with stock cooler and everything to 3.4ghz with stock voltages, just with multiplier, for 10% additional increase in benchmark.

But i do have a feeling this MSI board is trash, odd sata probs and stuff. Guess im ordering that asus one.

I have a rig with a Phenom 2 940 and an ECS 790GX board and surprisingly it does very well even when overclocked to 3.6ghz with Arma

Armed Assault is as poorly coded as the GTA IV to PC port is.

Pairing up a PhII 940 BE with a 790GX chipset . You need a 790FX/SB750 and a PhII 940 BE to fully take advantage of the PhII overclocking potential.

Not Entirely some of us can still overclock without the Overclocking software....I overclock through bios
