Better SLI support?

[Dwarden 1125]

i would like to point (again) out that SLI and Crossfire support is from 99.9% in hands of the IHV , manufacturers of hardware and theirs drivers ...

they need to put usable profiles for each game, card type and generation which covers the type of mode the dual/triple/quad GPU system will use to render the game

there is no standard for multiGPU solutions

(except some DX11.1 bonus but that don't affect the basics and it's not finalized yet)

so while developer may optimize his engine to better support how the title behave on the multiGPU system or ensure it's stable that's all he can do ...

also note that we support NVIDIA's Surround and AMD's Eyefinity to some level from time theirs libraries were first released ...

Well after reading around it seems I will need to OC my 1090T or upgrade to Sandy Bridge. Well that just sucks, I have never overclocked before and I'm afraid of frying my CPU.

seriously dont listen to these guys.You got plenty there to run arma 2 just fine.I have a phenom 2 965 be with 2 gtx 460's and i only get a 1 fps difference between 1 and 2 cards.SLI simply doesnt work in arma 2 the way it should.I seem to get an extra 15 fps in the actual arma benchmark but the game itself i get about the same.

You can speak from your experience and we can speak from ours.

I definitely see a very significant increase in FPS with SLI enabled.

I was wondering if Arma 3 will have better SLI support, currently I'm running 2x 560 GTX's and my performance is terrible. One card will give me 50+ FPS, running in SLI gives me only <40 FPS. So will Arma 3 have better SLI support?

Have you add -winxp in your shortcut? sli/crossfire -winxp!;)

for most people SLI doesnt work if it works for you great but it has been an on going issue since the game cameout.To sit here and have people tell this guy a 1090T doesnt cut it and he has to upgrade is ridiculous.BangTail what kind of card do you have in SLI and was there anything special you did to get them to work properly?

bigshotking,

Overclocking will not fry your CPU as long as you don't let it overheat or raise the voltage too much. If you raise the CPU frequency too high, the worst thing that will happen is a blue screen of death in which case you'll just have to reboot, go in the BIOS and either increase the voltage (only if you want to push the overclock) or lower the frequency and leave it at that.

I have a 960T which is very similar to your CPU, just with four cores (it's even the same kind of architecture). I was able to achieve a stable overclock on air without much difficulty, and I imagine you will be able to do the same. Basic overclocking isn't difficult, it just involves rebooting your computer and slowly bringing frequencies up, then running prime95 to test for stability. Raising voltages is more risky but should be safe as long as you stay within your CPU's specifications (I think maximum recommended voltage for you would be 1.4, that's what it is for me)

I can walk you through procedures for overclocking AMD. PM me if needed.

Contrary to what some of the people here are saying, a Phenom II can run ArmA 2 fairly well. Heck, I ran it on an Athlon and it was still playable.

Operation Blanket Statement is go.

GTX285s. Installed the driver, and selected SLi in the "Set SLi and PhysX Configuration window." Ohshi SLi enabled!

[Dwarden 1125]

remember it depends on driver You use, it must include the profiles

Heck, I ran it on an Athlon and it was still playable.

I've played through AII and OA on an heavily overclocked Athlon, and it was quite playable, though cities were very laggy.

2 x 3GB 580 (Specs are in spoiler) and there are no extra steps to get it working properly.

I really don't think you speak for 'most people' as I know plenty of people who have no issues with it (many of them on this forum).

My brother plays A2:CO on an Athlon II X2 and it runs rather fine. It's a bit choppy but definitely playable at 1-2k viewdistances.

I had an Athlon II x4 which ran even better. Chernogorsk and Zargabad would get a little laggy but the game ran quite well in general.

[CameronMcDonald 146]

The cities are both miles away better with SLi than without. Hell, even on one card the cities run so much better now than at release.

[banenwn 10]

well i game on and off with over 100 people on arma and only know a handful that said they got SLI to work properly, and even the ones that did they were only seeing a 10-15 fps increase,which isnt bad i guess but it isnt great either.Im using SLI GTX 460's myself and am thinking about just going to one card and getting a radeon 7950 in a few weeks unless i can get sli to work.I know how to enable SLI it just simply doesnt work maybe i need a new driver ill test a few.I have the latest right now though

Hey I'm currently running GTX570's in SLI and my screen has a constant tearing just when starting up. I've read that they're in work with Nvidia and so forth to help with these issues. Is there any reason to think that this will be soon or probably not until release? BTW, i run off just one when playing ARMA 3 due to the tearing.

[Harry_Flashman 1]

If your main purpose for buying a new computer is for playing ARMA3 it would be wise to wait until it is closer to release date, this way you can take full advantage of technology that is not yet available.

You mean new, future technology that wad not used in the development or testing of Arma 3? Kidding aside, I see no meaningful advantage in waiting unless you believe Intel is going introduce a new CPU with a vastly faster clock speed or designed for even more extreme OCing. Which, judging from the rumor mill, they're not. Realistically, there's not a meaningful technology advantage to waiting - unless the wait turns into a year or more. But there would be a bit of a price advantage. But probably just a small one.

Same, two 3gig 580s and SLi is running fine.

Wonder if the others are hitting the full vram mark not allowing the cards cpus to work properly?

SLI is working fine for me. I use the GeForce v320.00 Beta, but if I play around with the ATOC-Settings then I get purple Trees / Gras:

I believe it's a bug within the ATOC-Settings and not Driver related, as I mentioned here:

That can't be right, I just bout this CPU 6 months ago. It's 6 cores, at 3.2GHz... I can't possibly see why that would be the problem...

Here you can compare different CPU's, like your 1090T vs my 3770k:

Click

If a Game / App is not so well suited for Multi-Core-CPU's, then the Speed of a Single-Core is interesting, beside other factors like cache.

So if I have my 3770k @4200MHz and you your 1090T @3.2GHz, who would be better off ?
