black shark sli support

[matcat]

hi

i was just wondering if black shark supported sli?

 

thanks

From what ive read it doesnt support SLI or Crossfire. Someone with a a sli/crossfire setup or the dual GPU cards (4870x2, gtx295) will be able to tell you definatively however.

Hi,

 

It does.

 

SLI is actually something that is supported in the graphics driver, and not the software. Whether SLI offers any advantages depends on two things:

 

* Whether the app itself uses the GPU for what it was intended for (some apps merely use the GPU as a display device and nothing more, meaning there is no advantage)

 

* How much processing the GPU is doing as to whether additional processing capability can be used to the extent it is noticeable. If there is only enough work for one card, then additional cards will serve no useful purpose.

 

I run my card in SLI for 8x AA - it results in no performance hit compared to no AA (7950GX2).

 

Best regards,

Tango.

I have the Dell XPS laptop with SLI 8800m and it works great. I havnt turned off the SLI in the Nvidia panel to see if there is a performance difference but it does work. Note, I've also used the dual core mod I found here on the forums and that helped a bunch also. I've been running it in "High" mode and its flawless; of course the sim itself is a challenge but it does run smooth...

 

If I could only get the logitech force to work with it.... I think a HOTAS setup is definately gonna be the next thing, I wish they stocked dthe X52 or CH products locally....

I have both an XPS M1730 lappie with dual 8800GTX's and a desktop with 3 GTX280's in Tri-SLI.

 

No difference in performance with SLI. Seems entirely CPU bound.

No performance hit is not proof SLI works in DCS. You need to show there is a FPS difference with SLI switched on compared to off.

Again, just because DCS 'runs without crashing' with SLI enabled is not proof SLI actually works actually with regards to providing a FPS benefit.

 

Like you say in order to see if there is any benefit you would need to test FPS with one of the cores switched off.

But that means that you have SLi running on both machines. That's not a true test until you've tested one with it on and then with it off. Testing two machines with it active ... doesn't seem like a true test ... especially with two different models.

 

I do, however, agree with the CPU intensive theory. I ran the sim w/out affinity @2.6 an I was getting about 30 FPS. then with affinity scripts, I get about 42 FPS. After overclocking from 2.6 to 3.2 I now get about 48 FPS.

I had BS running pretty good with dual 9600GT's in SLi. It ran similarly without it in SLi mode as well.

... numbers? I also run two 9600-GT cards ... but the poor use of their Sli architecture seems to be something with the manufacturing of that card version. I have them running in Sli too and have seen only small improvements in many of my games. I'd like to hear what the 8800 guys get.

SLi with the 9600GTs worked just fine in other games like in FSX, World in Conflict, and CoD 4 with really good performance numbers. I only got more stable framerates in BS than anything...but I will state that I had an average of 80+ fps in online missions in FC in some servers.

[BTTW-DratsaB]

I have two 9800gtx, but I cant use sli because, like Lockon, I get flashing over cast clouds.

 

The best way to see if sli is working is to turn on SLI visual indicators in the nvidia control panel

The latest 178 drivers solve this problem...

[d0ppler]

I must disable SLI, since my computer crashes whenever i hover my mouse over a button in the menu (launcher) if SLI is enabled. Allthough it works if I'm not using fullscreen though, but thats out of the question for me anyways.

???

 

I wouldn't have selected SLI AA if it didn't. ;) It is explicitly a different mode of AA.

No one has yet described an objective benefit to SLI.

[-Nighthawk-]

DCS: Black Shark isn't big enough of a game for ATI / Nvidia to optimize drivers for, only major games like COD4, Far Cry 2 etc. get this.

 

Not to mention there isn't really a need for it, I can run it maxed out 1680x1050 with full AA on my HD4850 / AMD 5600+ (3.0GHz) at 40FPS+.

 

All though SLI / Crossfire is done via the drivers, a game can still be optimized to make best use of multiple cards through the engine.

SLI for BLACK SHARK

 

:thumbup: I have tested SLI in this game with two 260 GTX,

very nice images you get, wonderfull grafics .... if you drop one card still nice, but you will see more stairs .... that means SLI will draw smother lines for you in the Cockpit ... with above mentioned cards no stairs at all, usind up to date drivers,,,,, no manual settings in the SLI profile performed by me .... the FPS will be still disapointing, unless your multicore CPU is clocked in the range of 3,0 GHZ or above

so if you have to chose between upgrading CPU or opt for SLI ( me talking about systems with simular specs I use / 24inch using in game resolution of 1920*1200 )

If you run high resolutions (ie 1920x1200 and higher) and use AA and/or AF then there will be less of a performance hit in terms of your FPS. It will not really boost your FPS at lower resolutions because this game is more CPU dependant than it is GPU dependant. Ultimately most of the processing power of high end cards is unused unless your using a 27" or larger display.

 

Hopefully in newer versions of their graphics engine they are able to shift some of the load from the CPU to the GPU or at least put in more eye candy :)

 

Right now if you want better performance and don't have other games that would benefit from Sli/crossfire then you'd be better off to spend the money on a CPU /motherboard upgrade.

This is good advice. SLI does nothing for you in Black Shark right now. I would highly recommend a CPU upgrade over a SLI alternative.

[nachomaga]

Same here. I have Nvidia GTX 280 SLI and no difference in turn sli on and off (maybe have to take a card from the computer to do the test, but I´m lazy, hahaha).

 

Like others say, it´s better to upgrade your CPU. I upgraded from Q8200 2.33 to a Q9550 2.8 Quad OC 3.4 and its a huuuuuuge improvement (with the Affinity trick, of course).

 

Oh, sorry for my poor english, hehehe...

[Amuro]

SLI does work but the load balancing graph only fills up about 20-30% with 16x SLI AA which means the game isn't really optimized for it, and 4-way AFR seems to be the best rendering mode for DCS.

[nachomaga]

I forgot, I turn the SLI only for the card temp. Well, I realice that in "Split frame rendering mode", not only one card is working, and the temperature is slighty lower. Its goes this way: no-SLI: 72C - 57C. SLI on: 69C - 68C.

 

Anyway, not sure if this trick is really very useful. Perhaps to have a long-live video cards (that of course you´re going to change next year, hahahaha).

[slowhand]

hey guys...at what res are we talking about? from what i've read on other forums about SLI it really works only at real hi res..up around 2048x1536..or higher...i'm running 2 8500 gt 512 meg and i see no change in my fps from sli and my non sli setting..but i will say this when i run in SLI after fly'n for a lil bit i get this.. http://beta-api.joggle.com/media/?media_id=726F356354EF45FDB4F2FA34F853D5E3&sitename=bfam

It doesnt happen initially? If thats the case, then it looks like one or both of your cards are failing or are really overheating.
