Would a 2nd 2080ti using Nvidia Link ( SLI ) be worth doing in DCS

I am thinking of installing a 2nd 2080ti using the Nvidia Link ( like SLI ) but not sure if it would improve graphics, any thoughts??

cheers

I got up to about 83% scaling in my tests in 4K with high AA settings. Which is actually very good relative to other games. In 1080p not worth it.

 

In a nutshell, if the graphic setting is GPU bound it will benefit from 2 GPUS. It won't help with CPU bound settings like Visib Range, shadows, or anything that increases the quantity and frequency of draw calls. If you have the slot and the surplus wattage and can get a second card cheap, go for it. I think a lot of 1080 Ti and 2080 Ti owners would be pleasantly surprised. By my rough math you can beat the performance of a single 3090 with 2 2080 Ti's. I haven't tested this myself though. Once I get a 3090 I'll be able to say for sure. Key note, this is for 2D. No one has gotten SLI to work to with VR so don't bother.

 

I never tried testing on 1080p low settings specifically to see how high I could push the frame rate. But out over less dense areas and at high altitude I saw 160fps+ with everything maxed out. Pretty sure that's the rough CPU limit but I have yet to specifically test that.

 

This is all dependent on you being willing to use Nvidia Inspector and tweak the GPU driver manually. It's not officially supported, so don't put in a help ticket if you are having problems getting it to work.

 

You have to follow these steps word for word:

Not sure why some people keep saying SLI doesn't work in DCS, it works very well in fact, just at higher resolutions and AA settings.

I used to have SLI and used it in DCS but I just can’t recall the performance and it was years ago. Just realize that many situations in these flight sims will be CPU-limited and in those circumstances SLI won’t have any benefit.

Thanks guys

I think I will sit and watch prices etc!!
