crysis performance with D900c, single card or sli..

so i am curious if you can play crysis at max settings with this rig? if anyone tested the game at playable framerates please do tell the results and what system you have.

 

i dont think anyone has played it on max setting with good FPS not being oced. the few posts i read they play great at miedum setting

 

so then sli makes no difference for this game i take it?

 

The Crysis Demo is not optimized.
- its single-threaded
- its does not utilize full SLI setups

the Retail should hopefully do better.... it better.

 

lol WHAT? single-threaded? non-sli i can see but single-threaded?

if true don't bet on the retail game being mutli-threaded all of a sudden. i don't think they will re-write the game code after the game is released....wow...

then this game would definately be possible on the consoles like the xbox360 without any significant graphical hit if they code the game to run 6 threads at once like the xbox can handle.

 

that might be why they didnt do it, so it can hit other ave.

 

you can easily code with threading "disabled" for demos and then re-enable it for the full version.

Think of it like this. They know that their game will have to be able to handle single, dual, and quad core chips. If they can not manage what maps to what core, then the program would HAVE to be single threaded (because the single core is the lowest common denominator). Since they are offering multicore support, there must be something in their code (engine) that allows them to manage what gets processed in what thread. (a common programming practice since the advent of multicore processing.)

 

makes sense

 

then why not have an option for the end user to enable multi-threading or have the game auto-detect and choose itself if it can enable multi-threading? the game looks bad to the general population in that people think it just won't run well on their high end rig. i would think this would maybe hurt initial sales of the game.

 

Yes, it would be trivially easy to restrict a well-coded multi-threading capable game or application to one thread. However, they would be stupid to release a demo that is artificially handicapped in terms of performance unless they expect system requirements to be higher in the final product. Would you try to convince your potential buyers that your game is worse than it actually is?

 

Perhaps they're trying to drive up hardware sales . . . that's the only thing I can think of.

Either way, the Crysis demo is extremely demanding and if you can't run it at full settings than don't worry about it. Basically no one can.

 

It is easier to debug the code when it is running single threaded versus muti threaded. So in terms of coding it will be faster to bring the product to production. My guess is it went something like this:

1 Code is written to be multi thread and cross platform. Test in single thread to find problems fix in house and final test multi thread and different platforms.
2 Drivers had a lot of problems in vista so no SLI yet. Wait until close to relase and work out problems.

 

i did some searching on this and it appears that sli is not enabled in the game at all but people have gotten sli to work by hacking some files and showed an 80% increase in fps. but the single-threaded thingy still is up in the air i guess. they also hacked to enable very high settings in windows xp with direct x 9 with virtually no visual difference compared to very high settings in direct x 10 with vista.

 

Interesting... I just loaded up Crysis with SLI disabled, and my performance had actually improved... even though r_displayinfo 1 reports that my FPS is half of what it was with SLI enabled. But the game must be doing something with that second card, because I've checked the temperatures after a few hours of messing around in Crysis and the second GPU was only a few degrees cooler than the first.

So I think it's safe to assume:

1. The Crysis demo doesn't correctly support SLI.

and

2. r_displayinfo 1 reports incorrect numbers, at least for SLI setups.

You say people have hacked SLI support into the game. Do you have a link to any info about that?

 

i don't have the computer system to run the game so i don't know much about it besides general reading on the forums. i do not recall where i read it but it was a very informative sli forum. i will try to find it tomorrow when i check my internet history on my office computer.

 

the info is in here about sli. http://www.nvnews.net/vbulletin/showthread.php?t=101231

 

I am currently trying to get the Crysis demo properly working on the Dell XPS M1730 - ours has the 8700M-GT SLI. I found that no matter what I do, there is a skipping every few seconds the entire time I'm playing. I am going to try and disable SLI and see if that issue goes away.

Take a look at this:

i have read in the dell forum that the m1730 has issues with the 8700m sli and that games do not run properly while dell acknowledges the issues and is trying to resolve it but so far nothing. only 3dmark benchmark runs without issues but not games. go figure.

 

hehe...imagine blowing $5k on xps 1730...and getting this level of performance
..gotta love dell, huh?

 

I've read somewhere that officiailly the Demo does not scale well over multiple cores, neither on the CPU or Graphics cards. The full game will!

Concerning the graphics cards it is an issue that is being resolved but it seams the solution for problem does not lie only on the the Crysis team but also on NVIDIA SLI drivers for Vista.
