pubg 1070 sli?

[Quavooo]

I have two Asus Dual Gtx 1070's and they are connected to my motherboard and also have a nvidia HB bridge connecting the two together. I wanted to know what I need to do in order for the SLI to work properly in PlayerUnknown's Battlegrounds! Please and Thank you! Also I have an i7-7700k overclocked to 4.8 ghz, Corsair h60 liquid cooler, 750W PSU, Cyberpower ASRock motherboard and 16gb ram.

From the forums:

1. Go to nvidia control panel
2. Manage 3D settings
3. Program Settings Tab
4. Add game to list
5. SLI Rendering Mode - set Force Alternate Frame Rendering 2. Apply
6. Test it- If Alternate Frame Rendering 2 does not show an improvement, try Alternate Frame Rendering 1

FYI this game has poor SLI scaling, meaning the second GPU yields less than half an increase in FPS. I'm afraid this is going to be the future of multi-GPU and a reason I decided to abandon it permanently after nearly 20 years if first having SLI with 3Dfx Voodoo 2 cards.

I have tried all settings in that category. both frame renderings and single-GPU... I get 40 fps wtf

Are you married to 1070 SLI? Could always sell them and buy a 1080 Ti

From a quick Google I have seen people online complaining of worse fps with sli enabled in this game. Looks like sli is just not properly supported.

 

[slyverine]

Sli support from games is CRAP! I have never used myself but from what i have seen and heard, i will never go sli. Sell the second one, one 1070 is strong enough, keep the money and buy the 2070 when it releases and be happy!

as above... SLI has become a royal pain in the ass!

Also, while the performance in PUBG has improved a bit, the optimisation still isn't great.

Lately, SLI is just an afterthought at best for most game studios.

I ran SLI until recently and cannot see myself going back to it.

Another question, I did a Heaven benchmark with both gpus and with one gpu and for results I got- SLI: FPS:228.7| Min:39| Max:368 Single: FPS: 188| Min: 39| Max: 348. I noticed that both minimums were the same, and they happened to occur at the same scene for both trials. Is there possibly something else that is affecting my fps performance and causing a fps drop/stutter?

Most likely CPU. High fps is very CPU dependent and with all that gpu horsepower there will be times when the CPU is the limiting factor.

^^An i7 7700K on a Z270 motherboard will *not* be the limiting factor of the CPU with SLI 1070s. Especially running overclocked at 4.8GHz.

Now for the game itself, make sure you have the latest Nvidia WHQL drivers. As of June's 382.53, it supposedly created an SLI profile enabler for Battlegrounds in Nvidia's control panel (you'll need to manually add the .exe to it if you don't already have it in the running app list). Some have used these instructions, but apparently updated Nvidia drivers fixes it automatically. I do not have the game so cannot confirm.

One guy had this set up in the Global Profile setting of the Nvidia control panel:

Regarding Heaven, if I remember correctly the minimum FPS will remain near the same no matter if you have one or two GPUs. I haven't run it in over a year and no longer have SLI so I can't verify. But you should see higher max FPS than that in improvement with the second GPU enabled.

*EDIT - this is assuming you are running one monitor and not multiple monitors. Heaven can do screwy things with multiple monitor setups.

 

[sizzling]

Just monitor your cpu usage and I bet 1 or more cores hit 100% when you get to that part of the benchmark.

Hmm, I remember not capping 100% CPU on Heaven on my overclocked i5 4690K at 4.7GHz with 970 SLI. However I just looked at my test from two years ago just for performance comparison:

Render: Direct3D11
Mode: 1920x1080 8xAA fullscreen
Preset: Custom
Quality: Ultra
Tessellation: Extreme

Stock CPU (3.5GHz all four cores), single GPU:
FPS: 53.2
Score: 1341
Min FPS: 24.2
Max FPS: 111.9

4.6GHz CPU (all four cores), SLI:
FPS: 108.6
Score: 2735
Min FPS: 27.5
Max FPS: 229.4

 

[sizzling]

So overclocking your cpu raised your minimum fps by 13.6%. That supports my theory that its a cpu limitation.

 

[10tacle]

Not necessarily. SLI does not scale perfectly 50/50 even on Heaven. If I still had that SLI setup I'd run a test on a single GPU vs. SLI at the same CPU clock speed to see what performance improvement the CPU overclock does compared to single vs. SLI cards. Also keep in mind these settings (tessellation on Extreme specifically) are heavy on the GPU(s). Also if it truly was CPU limited, it would be spread across the board. Minimum FPS readings on any benchmark can be a strange duck and not reflective of a CPU limitation.
