ever since version 4.15 they have implemented sli into unreal engine 4

Real time visual FX rendering.

Not gaming.

You will never find a UE4 engine game that utilises both GPUs @ 100%.

I watched your stream, 90% of the time both your GPUS were @ 50-60% usage.

thats becasue i have vsync on capped at 100fps dude

[Kamiccolo]

im running 2x 1080 tis no wonder its only using 50-60% with vsync on capped at 100 fps

Why then, I cap my 1 1080ti @ 100fps and maintain that FPS all ultra 90% of the time.

But hey whatever man, if you're happy thats cool.

my monitor is 100hz asus pg348q 3440x1440. I dont run over 100 fps ever there is no point.

[Kamiccolo]

its because there is increased loads all over the map and gpu usage will spike. This way i will never drop below 100 fps and have a buttery smooth experience. Thats why I bought sli.

[Morethan2Letters]

We have the same monitor.

[Kamiccolo]

but again this is not just for me. Other users with say 980 tis or lower like my friend with his dual 680s can actually achive 100fps in this game or more.

[Kamiccolo]

at a higher resolution or even with our monitor

[Kamiccolo]

the point of sli is to achive what you cannot with 1 gpu. Running a 4k monitor is taxing and even running our monitor is insanly taxing with anything less than a 1080 ti

remember this is for the community not just extreamists like me but I like benifiting from it myself.

I get it, but the Developer and game engine have to support SLI or it wont work. I guess from having to disable SLI 90% of the time because a game ran better, I kind of soured to it. Cool tech that was worth it when GPUs weren't has powerful as they are now.

[Kamiccolo]

totally true and that is why if using this profile you have to disable ultra shadows and effects to very low. Both of those settings are implemented into the game by the developers. Unreal engine 4 does support it in its base form but since the developers add effects that are not sli supported the game then becomes unsupported.

The ultra shadows in the game are a form of Ambient occlusion and not a very good one at that. The effects added into the game as well are not good at all anyways to begin with and dosnt support sli.
From my own testing I figured this out which took a long time lol but since i figured out whats not supported then a custom sli profile can be created that nvidia wont do because the developers wont address the sli problem with those settings.

[Kamiccolo]

and nvidia will not tell you disable these settings to get sli working.
