Thank you very much, I have also tried this in the past and it does help slightly here and there, but it's not perfect, still not close to what the performance used to be.
But might try the latest release at some point again.
Ok. You can try also dxvk+rtss(scanlinesync) if you whant buttery smooth gameplay. For me with dxvk+rtss i have 120+ stabe fps where on d3d it drops to 40
ps and what performance fps you expect of fixed driver?
I expect close to where it used to be for me. I used to get minimum 75FPS in CPU intensive scenarios, now it drops the 29FPS in the same scenarios. If I use DXVK brings in up to 45-56FPS in those scenarios. Less than 60FPS results in bad input response on UT3.
Hi. What gpu and cpu you have? What video driver and what windows?
I can reproduce those(where you have drop fps) scernarios or places in UT3 on my PC?
ps rx580 20.12.1 here
Hi @deepforest , excuse me for only replying now.
I am currently using,
- my AMD FX 8350 CPU at stock settings,
- Latest version of Windows 10 Professional 64-bit,
- Latest Radeon Driver (21.5.1, please note the Windows version doesn't seem to matter, only that using any driver newer than 16.6.2),
- Having a better CPU does help slightly, but please note I was getting 90FPS where I am now getting 28FPS.
One of the best maps to test on is Deck, and I will attach the locations now, also note that resolution or settings doesn't matter, I will attach a screenshot where I got 28FPS on 640x480.
Ok sorry they are limiting on barely being able to upload an image, but the whole level is a mess, I'll upload the 640x480 one since it is the worst location:
Basically stand next to the portal and look towards the other-side of the radioactive pool.
Hi @deepforest , excuse me for only replying now.
No problem. Glad to hear you) And excuse me for my poor English)
Now i using:
-Win10x64 20H2(also have Win7x64)
-rx580(20.12.1)(but after 16.6.2 it doesn't matter)
-Ryzen 5 2600(at stock settings)
(before i had Xeon e1240 Sandy Bridge 2011y, i had 100fps where now i have 120 using Vulkan, at D3d i had drops to 40fps)
-lasted DXVK x32(not x64) dlls for UT3(you need use x32 dxvk dlls for x32 games and x64 dxvk dlls for x64 games)
And what situation you have at UT4?
This is map Unsaved, at Stinger location
May be so small fps at all games based on Unreal Engine 3 and 4 its problem of AMD drivers? I hear that Unreal Engine the best optimised for Nvidia not for Radeons.
Thank you for your response, don't worry English isn't my first language as well.
That Ryzen 5 2600 has very good IPC already. But you'll see if you strafe left and right a few times in that scene in DX9 you'll likely get frame drops to 48-54FPS, that's what happens to me by using the DXVK wrapper at least since my FPS is around 60 standing still in DXVK with that scene.
Thank you for your efforts to take that screenshot and prove the issue exists and most Radeon Hardware and newer driver versions than (16.6.2). I do not currently have Unreal Tournament (UE4) installed, but it was performing quite well on my system, I was getting 80-100FPS+ a lot of times.
I do not think AMD has to bad issues on UE4, since I own a lot of them and they play much better than Unreal Tournament 3, like PUBG, Ride 4, etc. I do however believe Unreal Engine 4 is slightly better optimized for Nvidia, since I was getting like 2-4FPS more on my GTX 1060 3GB in Ride 4 under max GPU load, where in Prey my RX 480 funny enough gets 20-30FPS more under max GPU load even when it is a DirectX 11 game. Don't know if they were maybe able to use ASync Compute in that game.
And then taking UE4 out of the equation, DirectX11 and OpenGL games tend to scale quite a lot better on Nvidia over the CPU than AMD Radeon does, I don't know why, if it is because of Deferred Contexts and Commands Lists that AMD left out apparently, but it is quite bothersome that they launched the first DX11 card, but in the majority of games their DX11 CPU Utilization leaves me in the dust.
Another thing about using DXVK is the input responses feel different at the same framerates, and I don't know if this is because Vulkan/DirectX12 are low level APIs.
So, why if you have 1060 you dont use it for UT3?
And what we must to do? Whait until AMD fix UT3 performance through drivers?
I do sometimes play it on my GTX 1060 3GB, but I mostly use my GTX 1060 for PhysX and I would prefer to play games on my Radeon since the input response feels a little more precise when at the same frame-rates, a game like Killing Floor 2 almost uses the GTX 1060 to 100% in PhysX while my RX 480 renders the rest of the game. Furthermore, I have found some games missing graphics on Radeon drivers and if I don't play with Radeon I will never report them and reporting them too late in a case like this it can take years before they decide to fix it.
I don't know why they can't provide a little feedback, in 2018/2019 they said they found the root cause and almost had a fix ready, and since the new website launched they have deleted that post of mine and have barely given any feedback on their fix since. The same with Crysis 3, their Driver seems to be hating some versions of CryEngine since 2016 as well. We had a huge post of it where the AMD user Colesdav made a lot of effort to post performance issues even on AMD's latest hardware.
