Freesync flicker with CF791 @ ultimate with new driver version

Hey,

I have extreme flickering of the screen (brightness flicker) when Freesync is in setting "Ultimate" when playing games. This is happening since a couple of versions of drivers. If I remember correctly the last working version was 18.6.1.

For sure the flickering is happening with 18.11.1 and 18.9.3 and only when the Ultimate mode is enabled.

Happening in World of Warcraft and Battlefield 1 / 5

It was not happening with any driver version before 18.6.1. In fact I tried 18.8.1 and 18.9.3 (and if I remember correctly 18.7.1) and installed 18.6.1 again which solved the problem. Now I have to use 18.11.1 because of Battlefield 5 and I am stuck with that problem.

I have a Vega 64 Liquid Cooled Edition and a Samsung 34CF791 connected via HDMI 2.0.

Since the problem disappears when installing an older driver version I am sure it is a problem with the new drivers and I am asking to investigate and fix the problem. I found other people reporting the same problem in other forums.

If you need more information, please don't hesitate to ask.

Best regards

Do you also have the same problem? If yes - can you please describe some details, e.g. which version(s) did work correctly with Freesync-ultimate and which versions do not work?

Re: Freesync flicker with CF791 @ ultimate with new driver version

I Have the same Issue.

17.12.1 is the last Version for me where FS over DP is working without Flickering.

I tried so much. I fidled around with the FS Range via CRU, i installed every single Driver Version, turned on/off every point in the Drivermenus.

I used HDMI and DP, bought a high quality DP Cable...Hell i even disconnected my old Soundcard from the System.

Nothing relliably helped. The only thing i can do is to return to 17.12.1.

I hate this Issue and honestly im considering to sell my Display and Vega and return to NVidia.

Re: Freesync flicker with CF791 @ ultimate with new driver version

It s more than a half of a year and they still didnt fix flickering issue since it started after 18.6.1. I dont know how can we get Amd to respond to this issue. I m wondering if there are other ways - like using older drivers ( 18.6.1 ) with game optimizations from the latest drivers or maybe getting freesync profile from 18.6.1 and copy it to the latest drivers.

amdmatt‌ help :smiley face

Re: Freesync flicker with CF791 @ ultimate with new driver version

For me as well - still the same issue. Tried every driver version ever since - no fix.

And since amdmatt‌ asked me to open a new thread for the problem and I never even got a reply I have to say that I am not happy about it.

It is clearly a driver issue and not even a response within half a year? Really..?  -_-

Re: Freesync flicker with CF791 @ ultimate with new driver version

We have fixed as much of the flickering as is possible with this monitor, we cannot improve on it any further. 

I have tested using older drivers and see the same flickering as with newer drivers. 

If you can give me a couple of clear examples of games that flicker on newer drivers but don't on a specific driver version (ie 18.6.1) please let me know as i use this monitor daily so will test it to see if i can reproduce it.

Do you use DP or HDMI?

Re: Freesync flicker with CF791 @ ultimate with new driver version

amdmatt - Thank you for the answer.

I retested again today to confirm what I remembered and described earlier by using the following approach:

- Uninstall installed version --> Restart --> Install Adrenalin --> Restart.

- Check if FreeSync is set so Utltimate in monitor settings and set to 48-100 Hz in Adrenalin

- Leave all settings in standard.

- Test games for flickering

- Set up the settings in Adrenalin I usually use (HBCC on, undervolting, etc.)

- Test same games again.

Start again at first point using another Adrenalin version.

Games I tested today: Battlefield 5, World of Warcraft

(Games I tested earlier but not again today: Battlefield 1, Pubg and more and I had the same issue with flickering)

The last version which is working with absolutely no flickering at all is: 18.6.1 (win10-64bit-radeon-software-adrenalin-edition-18.6.1-june13). I had most versions before 18.6.1 installed as well and I never noticed any flickering.

Every version I tried after 18.6.1 has flickering, including the current 19.2.3

I tried HDMI 2.0 and switched to Displayport two weeks ago. The problems occurs with both connections. Also all the other settings don't seem to affect the flickering.

The flickering is easy to spot when starting the game. E.g. in Battlefield I can see it clearly during the loading screen (at the bottom). During game or when a lot is moving on the screen the flickering is not that noticeable and only sometimes the whole screen flickers - looks like a rapid change in brightness.

The flickering is also not all the time, but appears only every 5 - 20 seconds or so. It seems to be related to what happens on the screen. Hard to explain, though.

And since the flickering is not noticeable at all when using 18.6.1 and immediately noticeable when using a later version - I am sure that it is related to the driver. Something did change after 18.6.1 within the Adrenalin version which is causing the flickering to be back.

Please tell me if there is anything else you need to know. I sincerely hope you can reproduce that behaviour.

@others with the same problem - please use the same approach to confirm that 18.6.1 is the last version without flickering using FreeSync with the Samsung 34CF791 set to "FreeSync Ultimate".
