SLI issues FPS no increase please help me

[lifty187]

Hi i have x2 gtx 1080ti i thought that by having on SLI it would boost my fps, when im playing PUBG im getting the same FPS around 50fps on 4k ultra and thats the same as if i was using 1 card?? and its like it for most games, SLI is enabled why am i not noticing a difference, ILL PAY DONATE ANYTHING for some 1 who can help me sort my sli out

3D Mark uses sli because they invested time and money making sure the program supports sli and is fully optimised.

Games have to be developed to use sli/crossfire for it to work but this adds to the development costs and time to develop the games. As sli/crossfire is only used by a small percentage of gamers the desire by developers to invest time and money into supporting something that very few people will use is dropping.

ive just been in pubg for 5 mins and temp of second card was still 29C does that mean its not working?? is it the game stopping the card or what?? ill now run test again and watch over my temps

I suggest you Google sli support or at least search Toms for that topic. You seem to have jumped into Sli without knowing its limitations and downsides. I personally tried sli many years ago but never went back to it.

exactly that i brought a overkill pc thinking it would just be all fine but reality is different now gonna run that test again see if other card heats up

We have established that PUBG doesn't support sli properly, that is why the second card is not working/heating up. It's not your system, it is the game.

Use MSIAfterburner, it shows you the % each gpu is being used. When you run 3D Mark both cards should show good usage and heat up.

Hmm saying overwatch reminded me of Win10s fullscreen optimisation feature added in creaters update. In overwatch has problems with it, not sure how extensive it is if more games are affected. Or if its been fixed yet im not sure, its been a while.

Worth a try. https://www.google.com.au/amp/s/mspoweruser.com/tip-fullscreen-optimizations-might-hurting-game-performance-windows-10/amp/

so in the 3dmark the card heats right up so i know its in use, so when im in pubg and the cards not heating up what could that mean, no SLI support?? there must be tho as people are using it, btw thanks for all your time this morning.

Well everything I read on the forums suggest PUBG does not properly support sli and it gives no real benefit. As I mentioned before don't trust everything on YouTube. If people are getting it to work then ask them on their video commentary how they did it seeing as the gaming forums say it doesn't work. If they genuinely are getting it to work they should be able to tell you how.
