8800GTX SLi on Crysis

[tunnel]

I fear i have done something wrong.

Just installed my Second 8800GTX in my sli config and i still only hitting 40FPS max on crysis.

No AA or QAA
All Settings Very High
Resolution 1024 x 768.

Something has got to be wrong isnt it?

[thideras]

Sounds like a processor limitation. Can you try a higher resolution?

[tunnel]

1024 x 1028 and still get similar readings.

[thideras]

1024 x 1028 and still get similar readings.You still get the same FPS? Then it definitely sounds like a processor limitation ;)

Crank up the resolution as high as possible.

[freakdiablo]

1024 x 1028 and still get similar readings.

similar readings as in still 40fps, or similar as in you get the same as only 1 card? If you are still hitting only 40fps yeah its probably cpu related

[tunnel]

Ok even at 1300 x 768 my fps still sucks.

Surely a E6600 OC'ed to 3.2 would cause no limitation. Could it not be drivers or another problem? I really hope i don't have to buy a new CPU.

http://www.toonultras.com/crysis.jpgActually, my E6400 @ 3.4 was bottlenecking my single 8800gts. I kicked it up to 3.6 and saw a pretty large jump in FPS in everything.

So...applying that to your case, I would say it is being heavily bottlenecked at those resolutions. Either up the CPU speed or go to a higher resolution. :shrug:

One way to test is to drop your CPU speed by 200mhz, see if the FPS follows. If it does, that is what the issue is.

I dont want to OC it anymore on stock cooling.

[thideras]

I dont want to OC it anymore on stock cooling.Then your only solution is running it at a higher resolution (bigger monitor) or selling/returning the second GTX. That is, if you want to see a difference.

Try my test though, see if it shows you anything.

I think a 28" is big enough. Ill try but it normally cuts out anything above 3.4

I seriously doubt this could all be down to my CPU.

Could you send a link for the latest SLi Drivers.

Newest drivers?

www.nvidia.com

[Neural Net]

Actually the latest (beta) drivers can be found on guru3d.com, and if you're running Vista, SLI is broken in regards to Crysis, apparently it's fixed with SP1. However as many have said, you need more CPU power, I'd ask Viper John whether a Dual or Quad core is best, I'm going Quad myself.

Is there specific Sli Drivers you have to get?

I got this driver 3-way NVIDIA SLI drivers from here http://www.slizone.com/page/slizone_downloads.html

That is the highest resolution for my TV.

I thought you were referring to a 28" LCD computer screen, my bad :)

[tunnel]

but if Sli, crysis and vista dont work then surely thats my problem.

[LilBuddy]

My single 9600GT gets 53fps in Crysis @ 1024x768.

I'd be asking for a refund!

[PhysX]

u need a Q66 atleast to get more fps.

[uberwoot]

SLI is good for higher res's. 1024X768 you only need one card and haveing sli at that res wont give you that much of a boost in preformance. But its a diffront story when you crank up the res.

[deathman20]

Indeed you got the power bump it up to 1600x1200 or 1920x1200. Something much larger to use the cards power.

[Shiggity]

Yeah I thought the biggest bonus to the 8800GTX was the amount of 384bit memory it has. With all that video memory you could probably get up to 1900x1200 and still get the same FPS.

[tunnel]

My TV only support 1300 x 768 as its highest res.

But surely even on 1 GTX i should be getting higher then 25 FPS on average.

[uberwoot]

yeah haveing 2 8800gtx's and running them at 1024X768 is like buying a indy car then doing daily driveing with it in the city never going over 45mph


new heatsink and oc your cpu some more and the fps will go up some. My E4400 gave me a nice boost when i went from 3.2 to 3.4 on it.

[tunnel]

Is 150fps on bishock with everything set to high and 1280 x 1024 resolution good?

Still downloading 3D Mark 06 will post score once finished.

[vixro]

2 8800GTX's seems pointless with such low reses, am I the only one who thinks this?

[thideras]

Is this any good?

He shouldn't be getting FPS that low in Crysis.

tunnel, are you running Vista?

Actually wouldn't that be slightly high for just 1 card? Considering his CPU speed?

[thideras]

[Neural Net]

I wouldn't use 3d mark as an indication of SLI working. Just run a game, but before you do open up your nvidia control panel, and under the "3d settings" option in the menu select "Show SLI visual indicators". You'll get a bar on the left hand side of the screen, and the green bars should move up and down to show that SLi is working properly.

Why are you using such low resolution?

I think you said you had a 28" monitor. Nearly everyone in the thread has said to use higher resolutions. For whatever reason, you seem to be reading over it or something.

1024x768 -> 1280x1024 is NOT a significant increase in resolution.

What is the max resolution that your monitor can handle?

[tunnel]

Monitor: 1280 x 1024
HDTV: 1360 x 768

I can't find where to set that Show SLi Visual Indicators.

Also what should SLI Performance mode be set to?

[Maverick0984]

Monitor: 1280 x 1024

Alright, well, 150FPS sounds fine.

[vixro]

I wasn't trying to be rude, I was just saying with reses like that the change in frames when adding more and more GPU power is practically linear with no change at all. Only when you are limited by the GPU will increasing the power have a real effect.


His 3dmark score sounds low for 2 cards and high for 1 card so it's hard to say.


Needs to load up GPUz from www.techpowerup.com and find out if he has 2 cards enabled or not.

Here's the setting:

http://img408.imageshack.us/img408/679/slidc7.th.jpg (http://img408.imageshack.us/my.php?image=slidc7.jpg)

SLI performance mode varies from application to application, it's usually best to just leave it like it is (the profiles for each game are in the drivers and the default for Crysis is "NVIDIA recommended: Single GPU". To my knowledge Crysis and SLI is very buggy and results in very bad performance. Apparently SP1 can make a difference (http://www.nvnews.net/vbulletin/showthread.php?t=104410)

[deathman20]

The PSU might be under strain too from the dual 8800GTX's. It should run it but might be another reason for not possible scores as well. HX620W if thats correct Tunnel.

[Neural Net]

The indicator bars are a better indication of working sli. GPU-Z shows my SLI disabled even though it's not.

[tunnel]

I found the Show SLI and it does appear in crysis but i still get crappy 30FPS.

PSU can take it.
I installed a new one today and its even certified for 8800GTX on the SLi website.

Also on GPUz there are 2 graphics cards in the drop down box. Although SLI is shown as disabled

I take it 13635 3DMarks is rubbish for my rig?

I think you're jumping to conclusions. As I've already said in this thread and many others... Performance in Vista with Crysis on SLI systems is essentially broken, often killing performance to below that of just one card. It "works" technically, but it doesn't do anything for performance.

I do have Vista 64Bit. So with the release of new drivers i can expect an increase in performance?

[Neural Net]

Oh, true lol :).... BUT, there's nothing wrong with 06. I get 14300 with my setup (SLI running fine). It's just extremely CPU limited at 1280x1024. If tunnel (or myself for that matter) had a 3.5Ghz or so Q6600/Q9450 then the score would be much, much higher.

tru.dat i bring in 16k with my rig



Yeah your score seems ok.

[Neural Net]

Yes, considering:

3.2Ghz I scored 13546 3DMarks
3.3Ghz I scored 14300 3DMarks

100Mhz makes such a difference because the CPU is the bottleneck. Add in a faster Quad and your scores will go up a lot, just look at uberwoot's post, and he's got a single 8800GT (oh the shame :beer:)!

As for Crysis, well I've mentioned that already. :)

[deathman20]

Run 06 once without the cards in SLI. Curious to know the results on that.

I mean my 8800GT with a CPU running around that speed, my old E6400 I got 12.5k range easily. His card is better than mine in that respect so I'd think he should be getting a bit more out of 3D Mark. While I see it CPU bound still would be just nice to see.

Well I get 12892 with one 8800GT (CPU at a lower 3Ghz though and Ram at 860Mhz not 950Mhz). If I boost that up to 3.3Ghz That would probably be around the 13200-13300 range.

[tunnel]

My Results are not looking to good for my CPU. Its currently at 3.2Ghz.

What do you guys think?

Look at the link I gave in post 37, hopefully a performance increase is due soon.

As for your latest 11k score is that with SLI disabled? If so that's a little low I would think, but it means that SLI is definitely working with your earlier score of 13k. Perhaps your scores are low because you're running Vista 64? I'm running Vista 32 and haven't heard great things about performance in the 64 version...

Yes that is with SLI disabled. IS there even much point in buying a Q6600.

And is an increase of 2000 good for another 8800GTX?

When is Vista SP1 released?

[jason4207]

2000 points indicates SLI is working. Try some other games w/ and w/o SLI enabled and see what difference it makes.

I think the GT/GTS do better in 06 b/c of the higher clocks, but when you crank the rez up you'll see the GTX pull ahead b/c of it's bandwidth.

[uberwoot]

Last time i hurd Vista SP1 was released but Vista still sucks even with it.

I don't think so because surely this would have been downloaded on MS Update?

[vixro]

Been out since February if you want to look for it. The official paper launch date hasn't happened yet, they guessed March for that and that's why you haven't seen it on Windows Update by normal means.


Vista is good and even better with the service pack, don't believe the above post. Probably has 1GB-2GB of RAM or probably never even used it before!

It should be available for Vista 64bit users via Windows Update (KB936330) but I think it has been pulled due to the installation problems it causes with some users.

[deathman20]

Its not officially out yet you can do a quick fix to the registery to install it.

With mine it fails on step 3 of install after reboot and I can't figure out why. Must be one of the "incompatible drivers" that they where talking about having issues but I have no clue what it is.

Is there even much point in my buying a Q6600?

Or will my E6600 OC'ed be good enough?

Is it possible to slipstream SP1 onto the original VISTA disc? If so, I may have to try it.

With that thing that MS released already for network installs if not mistaken.

I know I'd love to slipstream SP1 into my original install, think that would elievate some of the issues with doing the update that I have currently.

vLite

vLite

http://www.vlite.net/

Thanks. :beer:

vLite was my first guess. I've never used it, but I love nLite.

My main concern was if anyone has actually tried slipstreaming SP1 into VISTA and if it works well. Have you tried it thideras?

[deathman20]

Didn't know vLite could slipstream SP1.

It came to my attention that some of you expected to install Service Pack on the lite Vista, without some components.
Unfortunatelly that is not possible, nor it was ever expected to be because Service Pack is meant to update the whole installation, if it detects that something is missing it aborts.

So the only way to use vLite on SP1 is to use it on the preintegrated version, meaning you can configure the Vista DVD or ISO which already has SP1 in it.
Until Microsoft releases one you can try making your own by following this guide.
But be careful, it's not official nor easy method so it is recommended only for the experienced users.

Hotfixes will work fine even if all is removed, and the best thing is Windows Update will not list the hotfixes for the removed components. So please don't spread the false rumors, vLite is not aggressive as one might think before using it, not to mention that it was tested for 14 months before these recent publicity outbreaks.

Yup it can't be done yet.

[thideras]

Was worth a shot, I'm sure they can do it eventually.

[vixro]

Currently you can't slipstream the SP directly into Vista like you can with XP. It was removed in the betas and I don't think they planned on adding the feature to it anytime soon. The only method I can think of is reverse integrating.
