We AMD Radeon users need DX12 or Vulkan for this game

[XenoAliens]

There's actually not much to investigate because we've seen this low gpu usage stuttering problem in many DX11 titles like in Crysis 3 (original and remastered), Kingdom Come Deliverance, Assassin's Creed Origins and so on. AMD can't solve this or they are not willing to spend the money doing so we know for a certain. Adding DX12 or Vulkan API seems to be the only way.

Do not be sorry, be better. Do not use DX11 in 2022, use DX12 or Vulkan. If Sony you are paying attention, please inform the teams for your next ports of this.

Edit:
even DXVK won't help much:

Hell I hate to experiment combos on Sigrun under such fps. It's totally like playing on PS4 slim back in the days.

Except for God of War, you can fix the low GPU usage problem yourself for all other DX11 games.
The reason for the problem lies in the DeepSleep states of the AMD GPU's, which are not deactivated by old DX11 games. This causes that some CUs of the graphiccard fall asleep when the GPU load is low, meaning that the graphics card cannot generate a full load.

To avoid that, you have to disable all DS-States with the MPT (More Power Tool)

Additional Crysis 3 has a Windows-timing problem. While using the Windows System Timer Tool and set it to 0.5 or 1ms you will increase the Crysis 3 framerate a lot immediately. (valid for the non-remastered version)

What causes the God of War AMD problem?... i don't really know.

I will be checking those out, thanks. Still, it's pathetic AMD Radeon products are troublesome to use.

I have seen you mention this in other threads, and i did it. It didn't help with God Of War, but it solved another problem i didn't know i had. I play PUBG, and my RX5700xt is more than enough to deliver a super high fps count on 1080p mixed settings(very low, low, medium.). But my CPU struggles to maintain that sweet 144fps for my 144hz monitor(or so i thought). It turns out that the GPU was in so little usage, that out of nowhere it clocked down massively, decreasing the FPS, and then it clocks up bringing the good FPS back. Now i have a pretty much constant 144fps, and i'm sure this will help with other games as well.

Nice to hear that!

MorePowerTool method indeed worked. I've tested it with Crysis 3 Remastered and The Witcher 3. As for God of War problem, I believe only Nvidia knows answer to that now.

DX12 is needed for this game without a doubt, some areas are way more demanding on the cpu than necessary
broks shop in tyrs temple being one of them

[FUN_STACK]

There's a mod to use Vulkan API for this game. Google: "DXVK Vulkan at God of War"

Truth be told I've been using DXVK for a while now, and it's still not quite there. Far from ideal. You can check my videos out

DX12 or Vulkan will do. DX11 doesn't belong to 2022 xD

so much bs in one thread...
you have low GPU usage because you run a GPU faster than a 2080 Ti combined with a CPU that is slower than a i3 12100 in games.

a CPU bottleneck is not fixed with some "magic" just because AMD users ignore facts as usual.

Troll harder with 12100 OMEGALUL

btw, for all dxvk people: dxvk causes with GoW a massive loading stutter (vulkan need to much time to write his shader-cache), the max framerate will decrease a lot, and OKAY for AMD User dxvk will increase the minimum framerate by around 10fps.

So using a vulkan-translator eleminates some problems, but create new issues.

So that is no solution for the AMD memory-management issue in THIS Game.

Truth be told that's why I post this petition. I was experimenting DXVK and this was also what I found. That's why I wanted devs to look into it

Modded drivers sadly don't work or get detected in MPT, so there's no way to disable that dumb feature like you said. I've been using those as they are more stable and had less issues than with AMD official ones. Bad thing is that they didn't disabled that first in these ones lol.

the devs know where the problem is. give them some time to recode the important string.

MPT has nothing to do with your GPU driver. MPT write a additional registry-file for your GPU-firmware. So I'm a bit confused by what you wrote... did you mean a "modified bios"?

No. I mean actual modified drivers, like XtremeG or Amernime zone drivers that are in Guru3d
