GPU Usage lowers upon looking at far away scenery

[MrC1065]

So I just got to Bleakfall Barrows and when I look at the building, I get 60 FPS with 70% GPU usage. As soon as I look at the mountains, my GPU usage falls and so does my FPS. So whatever is causing my GPU usage to fall is causing me to get low FPS. Anyone have a fix for this?

Have you checked the rest of the hardware if something else is bottlenecking when you look at far away scenery?

Usually this is an indicator of poor draw call performance, usually attributed by poor single core CPU performance not feeding the gpu enough data because DX11 is still limited on draw calls still being single threaded.

Usually

yea, do you have gsync on, put it off -- same problem with gtx 1080 -- but now it works perfect 90Fps+

I would assume it's my CPU but the average usage is 50%, it's hardly using the hardware I have.

I have an RX 480 and not even a Freesync monitor so that can't be it.

Hm, it might very well be my CPU since the performance increased when I bumped up the resaolution to 1440p, which decreases draw cells. If it is a CPU bottleneck, then I'm kinda irritated since the game isn't even taking advantage of my entire CPU.

%50 doesnt mean anything, draw call performance is determined by the performance of a single core, one can be taxed at %98 and the rest are barely taxed, it will still bottleneck due to the nature of the crappy API

I personally have an RX480 + FX8350 @4.2GHz and it ran terribly until i turned off v-sync in the .ini and capped fps to maintain 60fps (because bugs at higgher fps)

I'm using AMD overdrive to view my core usage and it's 50% on all cores.

no, it doesnt decrease draw calls, that stays the same, the only difference is that the gpu has to render more pixels on screen so the perception of performance changes arent as noticle

DX 12 where are you when we need you :D

MSI Afterburner is reporting more frames, it clearly reduced draw cells if my CPU is the bottleneck.

draw calls cant be reduced by changing resolution, draw calls are reduced by manually going in and removing geometry

Well, in any case, I'm playing in 1440p I guess.

And this surprises you why? :)

As CPU load goes up, the GPU can no longer be supplied with a steady stream of commands to render the next frame. CPU load goes up when you ask the game to render miles and miles of terrain, simultaneously GPU usage goes down because the CPU's busy with non-render stuff.

Except CPU load actually isn't going up. It stays the same.
