[spyropt]

I can confirm the same issue
i haven't had the time to bisect the build were the flickering started

[Dani1977]

flickering in every stage, training, nexus, boletaria etc...

[psennermann]

with the same settings I can't even start the game, it always crashes at loading or logo screen...

[theoldsport]

I believe the flickering began around the time SPU LLVM was first merged, if that helps finding the exact PR/commit. I don't have much time to look myself at the moment.

[tommis15]

Yes, I'm also having the same issue with the flickering.

[isshininu]

Huh, I noticed black flickering when travel from Nexus to first Boletaria archstone. After that screen goes white flash somehow.

[trevorbennett]

I'm experiencing the same issue as @psennermann . I can't even hit the title screen, the emulator seems to freeze anywhere from the launch of the game, to the from software logo.

[psennermann]

It's almost a relief, finally someone else that's experiencing the same issue...I think PR responsible should be #4750 but I'm not 100% sure because according to the thread only ASMJIT should be "broken", while I'm experiencing crashes in LLVM as well...

[isshininu]

I think it's latest @kd-11 PR

[kd-11]

Which bug? I played about a half hour before merging, it does have sporadic flickering but I checked older builds with a patch to disable the hang and the flicker was still there. It regressed (flickering) some time back, not recently. Its just that it was not playable so no one noticed. As for the freezing, I cannot reproduce on Ryzen.

[psennermann]

No, it's not the latest kd-11, for me last working build (except ragdoll proble) was 6978, then with 6980 came out the crashes unrelated to radgoll problem, while I admit that latest builds 7xxx crash more often, so maybe the already existing issue was a little amplified by another PR...

[Sildurs-shaders]

Can't reproduce crashes on 7077, flickering mostly happens during inital load of the game / area.
Xeon x3440, gtx 960 398.36, vulkan, I don't get that much flickering with llvm recompiler.

[psennermann]

I don't think flickering are due to 7077: while bisecting builds for the other issue, I noticed some flickering in 69xx builds as well

[miho171]

Hi, have a i5 7600k TSX gtx 1080, with last build i can play several hours no problem, but once in a while game freeze at start logos like @psennermann experienced.

[Finoderi]

@psennermann I'm not sure it will help, but try to uncheck 'Run this program as an Administrator' in the rpcs3.exe's properties. For me Demon's Souls crushes more often when this option is enabled.

[trevorbennett]

For what little it's worth, I pulled the binary for 6998 and it ran fine. I don't currently have the time to regression test but the breaking change seems to have come in the last two weeks. Also unlike @miho171 it's a consistent failure for me on 7077.

[Joltee]

I have 8700k with gtx 1080oc running Windows 10 and I also have flickering issues. Flickering is happening everywhere, sometimes it crashes the game as the screen goes complete white.

[Dani1977]

thanks for reply; the flickering still present with 7117, I have try every setting in spu section but i haven't see any difference.
regards.

[FluffyToaster621]

If you're talking about the screen flickering white, then it's still happening in 7166

[Dani1977]

screen flickering white/black still happening in 7221

retest with #5013

[Dani1977]

hi, sure I can test but I don't know how to download the build.
thanks

[HenningJW]

@Dani1977 https://ci.appveyor.com/project/rpcs3/rpcs3/build/0.0.5-8bfe38b3/artifacts you can click on the green check mark on the newest code (the one furthest below) in the #5013 PR (pull request). Then click on details on AppVeyor for Windows builds and TravisCI for Linux.

[Dani1977]

@HenningJW , thanks .
@kd-11 , I try only windows version

[Dani1977]

Hi,
I tried the build 7298, Nexus, Boletaria 1-1 and 1-2 it seems that there are no more black/white flickering.

i try to do more levels .

I finally isolated the black flickering, but it needs a lot of work to fix properly. You can try this branch if you have this problem and report if it is improved or fixed.

[miho171]

@educobuci you've just resolved the painful 4 core condition one year long! seriously, tested vsync on my i5 7600k with version 7652 passed logos section (basically a miracle), loading save and a straight hour of gameplay. never happened in versions with spu llvm and async compiling implemented.

[kd-11]

Hanging on quad cores was fixed in a recent PR by GalCiv (RipleyTom). The remaining flicker issues are fixed in my fbo_fixes branch, but it may be a while before it is merged into master as well.

[miho171]

@kd-11 yeah, sorry. saw the game work and thought was the vsync just enabled for testing. too much excitement gave me to the head. by the way, great work, thank you.

[ovitus]

Still getting lots of white flicker with fbo_fixes branch. It's really distracting. I'm on Fedora 29.

[kd-11]

Use an older version of the branch. Had to restore some stuff to hide a few regressions which are a blocker for merging.

[kd-11]

The fix has been updated to be a little more friendly with WCB so it should work a little better. Expect rare blinking on that branch though, much less distracting but will take a lot longer to actually fix properly. Should be perfect in des_fbo_fixes once that branch is rebased properly, but the work in that branch is very experimental and not mergable.

[ovitus]

Was on the wrong branch.. flicker is nearly gone, it did come back in force once in the Nexus, also the lens flare glitch someone mentioned. Separate issue, but any chance of fixing the audio stutter? It's really terrible on Linux using PulseAudio and not much better on Windows. I have it set to ALSA now, which just mutes it entirely.

[ovitus]

This is very playable. Please resolve the Z-cull issue.. it's the second most annoying bug ever!

[ovitus]

Ok, adding this to config.yml this does the trick for now:
Disable ZCull Occlusion Queries: true

Keep up the good work.

[kd-11]

Fbo fixes is merged into master now so it should work correctly without any workarounds on the master branch. The des_fbo_fixes branch is missing a lot of work that went into fbo_fixes PR instead which is why zcull was broken on it.

[kd-11]

As for audio, you need #5456. If flickering is gone with master, update this issue so we can close it.

[Parthorisian]

@ovitus

.. flicker is nearly gone, it did come back in force once in the Nexus

Yep, flickering is almost gone except some small in World4-2 begin

[ovitus]

Yeah flickering happens randomly it seems, then fixes itself when I reload the game or warp somewhere else.

#5456 does fix the audio.. on WIndows with XAudio2. No solution for Linux I guess. I know these are experimental branches, but I wish there was a binary available, it's a slog compiling on Windows.

[HerrHulaHoop]

Binaries for Windows are available for all PRs.

To download windows builds from a Pull request on Github:

1. Go to the specific Pull request's page
2. Click on the Commits tab
3. Click on the ✔️ at the bottom (always click on the bottom-most green check mark)
4. Click on the details link next to the AppVeyor build
5. In the AppVeyor site linked, click on the Artifacts tab and download the file with the Deployment Name rpcs3. It is the largest file in the artifact list.

[ovitus]

Oh, wow hey now I see that:
https://ci.appveyor.com/project/kd-11/rpcs3/builds/21272375/artifacts

Thanks dude!

[ovitus]

Well things are looking and sounding good, but I'm getting frequent crashes on the latest build of the des_fbo_fixes branch. Going to test it a bit more on Linux now.

[kd-11]

I would advise not using that branch until it is rebased properly.

[ovitus]

It's actually running almost perfectly on Linux, sound and everything, very stable. I had snd_aloop enabled before which is why I wasn't hearing anything over ALSA...

Zcull is still disabled. I'm not able to enforce Vsync for some reason? Any ideas? I have official Nvidia drivers installed (Linux).

[kd-11]

Vsync on nvidia vulkan does not work in any application, rpcs3 included. You need to force it in nvidia driver if the option is available to you.

[ovitus]

I could have sworn I saw it working on Windows in RPCS3. I don't think the option is available in Linux via the Nvidia control panel. No big deal though, it's just vsync. Thanks again

[ovitus]

Fixed screen tearing on Linux through the Nvidia control panel. Checked “Force Full Composition Pipeline."

How would I know when this branch has been merged with the main release?

[daBloodyBlade77]

When do you think that the experimental branch will be merged to fix the flickering issue?

[kd-11]

des_fbo_fixes is not getting merged into master, at least not in its current form and even then not for a very long time. Most of the relevant parts were already merged into master already so users of the master branch should only very rarely experience flicker if at all. Ofc if it starts flickering too much just exit and restart or warp to a different area and it should fix itself.

[daBloodyBlade77]

Im experiencing constant flickering starting in the tutorial. Do you have any advice for fixing this. I have a Gtx 170ti and a Ryzen 1600.

[morten71]

I still have lots of flickering too: Both in Windows 10 and on Linux, and using OpenGL and Vulkan. Sometimes it's white flickering, and sometimes it's black.

My latest attempt was with version 7736 on Windows 10, and it came close to being unplayable at times. Warping to a different area, or restarting the emulator had no effect I could see.

I'm playing on an Intel i9 9900K and the GPU is an nvidia 1080 Ti

[ovitus]

It happens less using the des_fbo_fixes branch, but it still pops up occasionally, sometimes with vengeance. I'm about half way through my game now and everything else seems to run well for me. Reloading sometimes helps.

[Dani1977]

Hi,
with 7881 i have no more problem of flickering.
Thanks, Regards.

[kd-11]

Closing as fixed.
