Crysis SLI Performance Feedback

I've found that 2560x1600 is playable with high settings under XP.

I dont think anyone says SLI sux..It is good. But when you go into the GTX/Ultra costs..sometimes spending that extra $$ can be for a very little boost...sure you got your crysis fps from say...30~ to 45..that is nice playable frame rate..but is it really worth another GTX or a Ultra cost in SLI? You would think..spending that $ on another GPU would give you 60fps..

With that said..

2x8800GT in SLI..= hot -.-..not just in temps but those are pretty affordable..but the GTX/Ultra..SLI...now that is only for those who can afford it

I just posted this over on the incrysis forums, but its probably more relevant here:


Hi all,

I know there are quite a few performance related threads already, but I wanted to start a new one for those still having bad performance - under vista expecially, with SLI enabled machines. All of the things i did are suggested in various places in other threads, i just wanted to compile it all together and suggest people still having issues do this.

my rough specs:

intel core 2 duo (quad core one whatever it is called (2.66ghz)
4gb OCZ ram
2x BFG 8800 GTX 768mb (SLI enabled)
30" samsung lcd
creative X-fi extreame gamer sound card


I like many others had very bad performance running in SLI, only getting around 10 fps MAX in the opening level of crysis, with all settings at high and resolutions of 1900x1200 or above..

I had to turn settings down to medium, and play at 1024x768 to get any sort of fps above 20..

after a few steps I'm about to outline below, I can now play at 1900x1200, or even at my 30" screens native res of 2560x1600 , all settings at high, and get average fps of 25-35 fps which for me is a big imporvement. After I get around to trying some custom system.cfg this may well increase!

what am i trying to demonstrate?:

SLI does work in crysis - and works pretty well!
Crysis is fairly well optimised and if you have a decent rig you will see the benefits!
Crysis runs prefectly fine under Vista (especially 64 bit)

so what did i do?

well, in this order:

UNINSTALL:

uninstall crysis
uninstall punkbuster
uninstall gamespy comrade
uninstall nhancer
uninstall nvidia drivers
uninstall sound card drivers

now, i also UNINSTALLED the following vista hotfixes :

http://www.nvidia.com/object/windows_vi … fixes.html

run a good registry cleaning app - i ran CCleaner.

RESTART.

////////////////////////////

INSTALL:

again to make sure - run a good registry cleaning app - i ran CCleaner.

download and reinstall the hotfixes again, one after the other.
http://www.nvidia.com/object/windows_vi … fixes.html

RESTART.

install the latest sound card drivers.

RESTART.

install the latest nvidia beta drivers (169.12 I believe)

RESTART.

go into nvidia control panel and ENABLE SLI.
go into nvidia control panel global settings and turn on SINGLE DISPLAY PERFORMANCE MODE.
go into nvidia control panel global settings and turn OFF all antialiasing related settings.

REINSTALL CRYSIS.

go into nvidia control panel, and under the crysis settings make sure SLI is set to CUSTOM (it should be automatically)

DONE!

ive been running crysis 64bit in DX9 and its now ace! - all due to just doing the basic steps of setting up a clean install. Even DX10 runs WAY better (a bit of stuttering though)

i highly recommend it to anyone before they start mucking around with custom cfgs. custom cfgs wont fix a poorly maintained machine.

obviously this for people running vista and SLI - stop complaining about performance until you have gone back and cleaned up your machine. i learned my lesson !

Crytek have made a great game, an AMAZING engine, that will only get better with time and patches. nvidia are still ironing out their drivers but they ARE getting better - and Vista runs fine but might need a bit of assistance smile

as for EA...........well.........Bollocks.

Cheers bud, but the links are bad

Since cryisis demo i run with SLI ON, so welcome to the club of Sli Ghost Users, no one would believe that you know how to clean and set up your machine.
Good luck!!

edit>> i forget, in the 1st page of this thread i post a similar "how to" , using CCleaner too here, so, i say that in Demo time. Today there are people with expensive highend machines and they dont know how to clean and install a simple driver. This world is crazy.

all very high dx9 tweak, under vista64, sorry but fraps goes to the floor, I play without mouse, cause i hold the cam with the right hand. This canon!camera dont give more quality, sorry.
But u can see that it runs great.

2 x 8800 GT SLI is only decent at 1600 x 1200 or less. At 1920 x1200 and above, it will get its ass handed to it from even a single 8800 GTX in DX10 apps. The 256 bit, 512 MB item is a big bottleneck at high resolutions. If it is DX9, then 8800 GT SLI does rock since memory requirements are much lighter.

A single GTX proved to be twice as fast versus the GT in DX10 games at high resolutions with good in game AA and AF settings. . Results.

I knew it!

Glad I bought a 8800GTX (coming soon). Hoping I will be able to play it at 1920x1200 with most things high.

SLI


SINGLE

Can you take some screenshots using crysis's internal fps monitor. That's more accurate cos it's shows high-low fps too. I've got 8800gt's in sli and while the fps is high, it's not as smooth as a single gpu if it could achieve that framerate. Example, I'm getting 41fps in 1920x1200 all high in dx9, low 15 high 70. Now that's standing still, ie. not moving! That's not from a time demo, that's just walking around the start.

If you run Vista and you enable SLI on Crysis it runs terrible. It's so slugish. I suggest to stick with single card. Vista and SLI sucks big time...

Damn.... glad I didn't decide to get an SLI mobo then! Since using Vista full time and reading such bad reports of SLI it sounded better to avoid it than go for it.

Maybe in 6 months it will be better

it seems very smooth !

I'm no good at driver cleaning. The programs don't seem to work for me. Fresh format is the only way to be sure
