@B6: How far down the road is official SLI support?

[RickRuski]

Yes, I too would like some official support. There have been conflicting statements from the developers about Sli/Crossfire. Early in the piece Luthier stated that they had broken the support for multi cards just prior to release and hadn't fixed it as yet. Later there was another statement from one of the team to say they thought it was working. I have experimented with Nvidia inspector and got the best that I can at the moment (which gives me nearly double the fps that of one of my single cards). Some are blaming Sli for the micro stutters that we have with the sim, strange that other sims are running smooth with Sli (RoF for one modern sim) and the stutters are still there for a lot that are only running single cards.

why buy two cards when you can buy one really good and expensive card...


its not like when you use sli or Xfire, the two cards capabilities are cumulative....its not like putting 2 1gb cards together allows you to use 2gb of VMemory

its just a waste of money....

now if you buy two of the most expensive and best card and put those together that makes a little more sense...

but doing what i see alot of people doing buy cheap or middle of the road cards and puttin the two together makes no sense....might as well just buy one really good and expenseive card...

we don't have even a proper AA
And you ask for SLI..

Have you tried the new nvidia beta drivers, use WRC 2010 from the programs list in nvidia control panel, FXAA and adaptive sync work.

Good luck!

My PC was working so well I decided to fix it, will I never learn? Anyway, it eventually, inevitably, led to a format and clean install.

My reinstall has not yet included the beta Nvidia drivers (301.34), which I thought were the reason the profile editor found launcher.exe rather than naming it WRC2010 on my system. With the clean system and official release drivers it now sees launcher and keeps the correct name too.

SLI seems to work well with 1.6 here, better than 1.5, as does AA. I force alternate rendering, which results in both GPUs running at around 70% (I only use 1 GTX590 for Cliffs) and only the slightest stutter on occasion.

I used to inject FXAA before the beta Nvidia drivers but with the clean install AA is good enough on 1.6 without FXAA.

I know this is not scientific but my system had become cluttered with lots of so-called performance improving software, Beta drivers and bespoke system settings and for me a clean basic system and game installation works as well if not better than with all the game and system tweaks.

Cheers,

Septic.

Don't know if both of your cards are from the same stable and exactly the same, if not then they may need adjustment with a software like EVGA Precision tool or similar. For Sli to work both cards must have the same V/ram (you can't mix a 1.5gb card with a 2gb card etc). My two cards are from different stables but I have clocked and voltaged them the same using Nvidia inspector, then synced both cards with PT. At the moment I have also used the fps limiter built into PT to limit the fps to 30fps. Sure I'm getting stutters but minor (micro stutters unless I'm down very low chasing a 109 or whatever) when up over about 2500 mts they virtually disappear. My two cards aren't that powerful but I'm getting good results through experimenting with settings. Don't believe what is being said about stutters being caused by Sli, if that was the case then all those running single cards wouldn't have stutters but a lot of them have (infact if they were all honest most are). My son has a quad core and a 560ti single card and has shelved Cod because of the stutters he is getting and is playing Rof where that runs silky smooth for him. I use a combination of Nvidia inspector and PT to get the results that I have, use the overclocking part of Nvidia inspector to adjust your clocks etc, it isn't just for over clocking you can use that to de-clock as well. Also in Nvidia control panel did you adjust the physics setting to CPU, this should take the load being used for physics off the Graphics cards.

AFAIK ClOD does not use Nvidia´s PHYSIX feature, so it should not make any difference.

I would like proper SLI support as well.

[RickRuski]

Don't knock Sli people until you have tried it. It works fine with most sims, this is the only one that I play that stutters. If you look at some of the posts others that have only one card are having the same problems that Sli gets blamed for. I've 2 x gts 450's (don't laugh) in Sli and have good frame rates (single play London Attack 40--60fps and over water in other single missions up to 90fps). My son has a single 560ti and doesn't get those frame rates or as smooth, he's even shelved CoD until there's been some major improvement. I've found that it's the ground rendering that seems to be the problem, once I'm up over 3000 mtrs there's no noticeable stuttering. Guess that is the hight limit for missions, during the WW2 citizens said that a lot of combat was not visable from the ground just the trails of aircraft.

What settings are you using in Nvidia Inspector to get SLI to work?
