Hmm, in retrospect, since I use DXVK Async, why do I need to bother with testing this Preview driver?

Chastity:

No, 22.5.1 has the older DX11 library. The May Preview driver has the newer components and driver.
thank man

Somebody tested this driver with GoW ?

Wow...the 1% looks very good. Hopefully that fixes the stuttering in that game.

I have a small bug i'm still trying to figure out. with MPC-HC (1.9.21.2), i get a greenscreen within a minute of playing a video. tried different videos with different codecs, tried madvr, evr, evr-cp, different output formats and colour depths. still trying different things to see if i can find out what exactly is causing it, but so far no go. other than that, driver is working well with the games i've tried. using same OC as previous drivers. edit:: had to disable hardware acceleration in lav video options. any selected option there made mpc-hc greenscreen. seems to work properly with it disabled. edit2:: it turns out the issue was an option in MPT in the PowerPlay Features. MM_DPM_PG is on by default. if you turn it off (as i have during OC testing) then the issues above happen on my system. not sure if it'll be the same with everyone, but as long as I keep that on, no issues crop up.

Spider-Vice:

This driver has all the same bugs as the Windows 11 "insider" driver, including random stuttering when hovering over links or clickable surfaces in Chrome, or the "typing" indicator becoming white in text editors. Slowdowns with window animations as well such as minimising windows.
Known issue that should be hopefully fixed in the future. Not sure of the cause but a few others as myself also get this problem but they said they do have a fix coming in the future for this.

Also confirming that this driver works on Vega56 (64 BIOS). First results (TimeSpy, FireStrike, SotTR bench), good enough.

It should work with hardware acceleration on. It works fine for me (DX11 and automatic/native device for LAV options). Do you have an example video file that has a problem?

The peformance enhancement is REAL. Since the game released, I had HUGE drops inside smoke clouds in PUBG. This was across the next cards: RX 580 then the VEGA 56 and now the 5600XT. I always had drops to the low 40 and even 30s if there were more than 2 smoke grenades thrown. Now they are GONE for good. An steady 68 fps out of 68 fps. Amazing drivers so far!

What are they doing differently to increase performance so much?

Good to see these improvements making their way to AMD's driver following NVIDIA's way earlier D3D11 optimizations among what other improvements are in this driver that is either a 22.5.2 preview or a fork from what will be a future driver branch and with RDNA3 when that comes out. Also bodes well for future improvements if this is what is landing now as code cleanup and bug fixes and other enhancements are underway. Liking what I am seeing from tests and such, really nice improvements. 🙂

This doesn't enable DCL's, but it enables API Multithreading for DX11 and OpenGL by treating them more like Mantle and DX12 using Platform Abstraction Layer

AMD driver supports DX11 mutlithreading and PAL since beginning. It only doesn't supports DCL. Can you please elaborate on what did you mean by that?

Krteq:

without DCL compliance, no it didn't. D3D11MT is directly reliant on DCL capability, without DCL a driver claiming D3D11MT is just doing everything in a single core serial fashion which completely negates the point of D3D11MT. Infact, its been demonstrated that without DCL, D3D11MT hurts performance as batching gets more complex.
Krteq:

and PAL since beginning
the preview is the first to implement PAL for the d3d11 and opengl umds, these treat the games as if DCL is enabled like DXVK did) but it doesn't expose DCL to tools that can verify the capability is present.

CPC_RedDawn:

Just played around 30 minutes of Witcher 3, at least 10fps more and zero hitching too. I used to use DXVK to run in vulkun but this driver has made DX11 not a lot better but a nice improvement.
Many haven't realised that running DXVK on AMD cards gives FPS boost on many games and in CPU bound scenarios Nvidia users too. (all those quad core intels for example).
