As title,
I'm playing The Witcher 3 maxed out on my 1920x1200 with a 4x DSR with the uniformity settings set to 0%, I don't like the blurry that uniformity setting add.

I'm excited, the DSR on the witcher looks amazing but at more than 4K my two GTX980Ti can't sustain 60FPS on every scenes.
It stays on 45FPS on average, it's pretty smooth but not enough for my tastes.

Do you think that adding another card will scale well enough in 4K?
 
I think it would be a waste of money. Why don't you just turn down the resolution to something more reasonable? At 1920x1200 I doubt there is much difference to be seen at over 4K settings anyway.

Grass, foliage, trees, landscapes are completely awesome in 4k, nothing comparable with 1200p
 
Try turning down foliage distance to Medium. Does TW3 even scale well at Tri-SLI?

I run Tri SLI as per my sig playing Witcher 3 and it scales pretty well. Generally GPU usage across all three gpu's is 80-90 something percent across the board. I play at 1440P as a reference.
 
As far as I know. Tri-SLI for gaming is more than likely a waste of money. A lot of games have issues with dual GPU's alone. The third can sometimes see very little gain

It's not a waste of money as alot of games scale very well and when it works its amazing. Albeit there are games that present a problem with regular SLI as well as tri sli. In the case of the witcher 3 I have had good results with very good scaling. I really don't know what else to tell ya.

This guy has the right idea. you are playing at 1200p...get a better screen before going tri sli. I was reading an article today, since I seen a few good 980ti used deals ($550ish), and tri sli is not worth the money for the increase you will get....especially on 1200p.

Edit: Heh, as I look at the other posts, it was the article AceGoob presented to you.
 
Absolute madness buying another 980ti so you can use 4k DSR to be honest, buy an actual 4k screen instead with the money.

I have money for the 4k screen and for another card, I have never bought a 4k screen because I always thought that current cards were not able to drive games in 4k at 60fps maxed out. But now with a tri way it could be possible, I think.
 
According to the article linked above - you'll see an average of 46.9 FPS with Tri-SLI 980 Tis at 4K in the Witcher 3. A gain of 17% over 2 way SLI.

Go ahead and waste your money. I'll laugh with you!
 
Set water detail to Medium.

Problem solved.

Since patch 1.0.6 multi-GPU water tessellation has been broken, it's MUCH slower than a single GPU. I bet your fps is crap anytime you are are near a large body of water.
 
There has been a documented issue with SLI scaling and the Witcher 3 since about 2 or 3 patches ago. SLI scaling is broken and you cannot get your video cards to scale to max with the game now. I believe it has something to do with how the developer changed the coding with Anti-Aliasing.

Using afterburner, my OSD will show a max FPS of around 40. The scaling on my top card will not go above 70%, and the second card is usually worse. The other issue is that if I turn all settings to low and disable post-processing, my FPS still stays at 40 FPS! It really sucks. There is a temp fix that one of the NVidia Forum members posted. They found an SLI protocol that works fairly well and boosts the scaling to above 80 FPS on both cards, but the FPS only increases to 45-50 FPS. I hope it gets addressed soon. Don't waste your money on a 3rd card.

EDIT- ^^ I just read your post Dragon. So, is Tessellation the issue? I will set it to medium and see if that fixes it. You are correct and my FPS stays capped at 40....

At 1200p my fps average 110fps at 4k it average 45-50fps, I don't think that I have the scaling problem, Ami wrong?

I did not know about these issues. In all honesty i have the game installed and updated on steam but i haven't played it in a couple of months or more. I guess the last time i played it was probably when these issues were not present. I did have very good tri sli scaling last time i played. That really sucks to hear.

absolutely not my case.
I have the genuine game with the latest patch and the latest nvidia driver with the system in signature and at 1200P I get a solid 110FPS with the game maxed out.
Never go under 105FPS and I have peaks of 140FPS.

Nothing possible without a good scaling on both cards.
PS: Afterburner says that the cards are used from 98% to 99% al the time.

Kind of confusing with your initial post and your last post. Well, if I remember correctly, with my Dell U3011, I had the game capped at 60 FPS and never had an issue, but if you see my sig, I actually game at 4K with a 4K Samsung JS9000, so perhaps that is the reason, albeit on the NVidia forum I pasted, people are having issues with scaling with resolutions lower then 4k.
 
Buy your third card from Amazon as they have a very good return policy. If it doesn't scale properly send it back. I'd definitely go with the 4K GSYNC monitor option at the same time. Preferably something large.
 
The more you spend the harder you fall. Just think when pascal comes out the 350 gpu is going to be beating those TIs effectively making those worth and 300 maybe less if pascal has full dx12 suport.

Imho there are too expectations on Kepler.
Imho if it will give a 30% improvements we will be lucky.

In the first post I talked about 4k and at 4k SLI scales well but is not enough to maintain 60fps
In the last postI talked about 1200p where my SLI average 110fps with annexcellent scaling

I was being sarcastic. Could you post a Screen cap of your OSD showing SLI scaling at 98-99% on both cards? Take a screen cap by some water if you don't mind. I'm running on a true 4k panel not DSR and I don't get that high of scaling, as well as many others have posted on different forums. Also, over 100 sustained FPS with everything maxed with hair works on as well? 1200 res to 4k is a jump, but something seems off with the numbers you are quoting
