PC - HDR - Windows Creators - SLi (performance issues)

SLI has always been a problem with |MEA unfortunately was a problem for me as well. The only answer I've found is to basically disable it as the game runs better without it.

Also, you have to have a monitor or TV that has HDR support. Very few Monitors right now that support HDR-10 none of them have Dolby Vision yet. Best to turn off HDR if you can't use it.

Not that I take pleasure in folks having problems with SLI - but this is just one more example of why I choose not to go in that direction. Single card solutions are the way to go for my budget. It would be different if folks got twice the performance (for twice the budget hit) and the feature was better supported... sadly this is not the case.

I'm certain that this isn't the answer that you want to hear, but SLI is becoming a major pain in the ass and Nvidia seems to be slowly phasing it out. With the 10 series of cards, only the highest end of the cards even support SLI and only in 2-way configurations. Support for it is becoming worse and worse as Nvidia pushes driver updates. SLI profiles are now coming out broken more often then working. Even game developers are starting to leave SLI by the wayside (not that game devs ever supported SLI well to begin with) and a lot of modern game engines directly conflict with the technology out of the gate.

At its most basic level, SLI is an intricate driver hack that isn't really supported by the OS or the software that runs on it. Basically the way it works is that the driver tricks the OS and application to only see one video adapter. The driver then controls the 2 GPUs, balancing the load and synchronizing the output of the 2 cards. As with any non-native feature, there are bound to be problems.

The only real answer I have you you is to ditch the seemingly sinking ship that is SLI technology and go with the fastest single card you can afford.

I too had a pair of 980 Ti's that got great performance and a pair of 780s prior that again, performed well... in games that supported SLI well.

Every other game either saw no change in performance, a decrease in performance, or graphical glitches, which I of course expected and disabled SLI accordingly.

The problem is however, that games rarely come out that work well with SLI and the problem is only getting worse.

Most games now a days come out with atrocious SLI support that is at best fixed a couple months after release or, at worst, never fixed at all.

I got sick of dealing with the bullshit and went to a single 1080 Ti and couldn't be happier.

I tried it before too and I concur.

As I said, I have a 2016 LG OLED TV, they are not low-end, in fact they are the most high end TVs you can get, and it supports both HDR and Dolby Vision. 

But to continue on with my OP, I loaded up MEA today and it seems SLi is once again not scaling properly with any of the latest drivers. The only way it will work properly is if I use 378.92 or lower, anything higher results in 50% usage.

TBH I have been using SLi since GTX 780 days, GTX 780 SLI > GTX 980 SLi > GTX 980 Ti SLi > GTX 1080 SLi > GTX 1080 Ti SLi and I actually have never had any problems with SLi in the games I was playing over those years up until now! So it is pretty damm saddening!

The only other thing would be your not using the right HDMI Cable need a cable that is HDMI 2.0b compliant
