Hi, im playing Battlefield 1 and on my Sli 1080’s i cant get more the 60% usage per card, is anyone with a sli setup having the same issue?
I notice a lot of stutter also, it runs smoother with single gpu
DX12 AMD runs away with. Nvidia takes DX11… both in single GPU. Nvidia works better in multi GPU DX11… and DX12 multi adapter support has not been implemented… Fing DICE…
SLI doesn’t really work very well. its there but its rubbish. No company’s really do alot to cater for it beyond the minimum. I used to have 3 screens an 2 cards an never had good SLI. till I got rid of 2 screens bout a single high end card an never looked back.
Current driver 373.06 has a BF1 SLI profile enabled however on some startups of BF1, 1 or more cards will stay in low-power mode (Dreaded 405mhz lock). Ive got 3-way SLI on GTX980Ti and can confirm it does work well in DX11.
If your GPU usage doesn’t go above 60% a few things can cause this.
Vsync is enabled
Your CPU isn’t powerful enough to run those two cards + BF1
but, only when i look in a specific direction (or down) i can see both gpu’s at 90% usage, but as soon as i change direction with the soldier, then the usage drop under 60% or 50%, it isn`t normal.
What fps are you getting? If its anything above 60fps then theres no issue. What you want to see is lots of frames with little performance. It means the game is optimized.
Have you tried disabling G-Sync?
I`m getting average 60 fps with single gpu mode with no frame drops and butter smooth gameplay, when i activate sli profile fps goes up to 80-90, but only in certain moments. There are big frame drops (50-60 fps loss) because for the most of the time both cards never go above 50%-55% usage.
Thats more down to optimizing SLI for the game. The current profile is still a little buggy. For 3-way it wouldn’t even use the 3rd card unless i used Nvidia Inspector and set the “Number of GPUs to use” from AUTO to THREE. Judging from the driver profile it will support 4-way.
I get a similar issue your describing. I max out on a single card, but with 3-way they all sit at 40-60% but still making about 70fps @4K. It just means the engine isn’t fully optimized for SLI. A couple of patches in and it should be sorted.
Its not just the drivers, the game engine also needs to be optimized for SLI. At the moment with the latest drivers my cards will sit at about 75% usage rendering an average of 70fps. I have noticed however that under certain conditions my usage and fps drop (Heavy firefight and explosions). This could indicate an engine issue (IE needs optimizing). It could be due to the 4K resolution im running as there are render limits to a game engine. You can only assign so much memory and time to completing a set task before the GPU is required to render the frame. (Usually under 16ms).
So it might be a couple of patches down the road that they are able to squeeze some more performance out of the game engine.
