Hello
For example I show a graph of CS2 with custom res 960x540 (no gpu scaling, this res goes to monitor), low details and fps_max 64 with Freesync enabled and there seems to be some sort of stutter problem happening.
It's not the frametime stutter since frametime are fine but as you can see in CapFrameX "Until Display Time" is not correct and this is what is causing the stutters on screen. I can clearly see the stutters on screen when playing the game using freesync.
There seems to be a correlation between the stutters and low gpu usage and specifically fluctuating VRAM frequency. I can see vram frequency fluctuate like crazy when playing the game like this. The vram frequency of this gpu should be about 1750Mhz max but monitoring (using amd software and hwinfo) shows over 2200-2300Mhz spikes which is weird.
I have found a sort of a "fix" for this issue. If I toggle the Amd overlay On that fixes the issue. I think it stresses the gpu just enough to stabilize things. There is no crazy vram frequency fluctuations, the "until displayed times" are fine and no stutter.
I think I have had this problem with other games too. For example playing World War Z in 1080p where toggling the amd overlay on would result in noticeable smoother gaming experience in some parts of the game when using freesync. No graphs of this, just my own observation.
Can AMD release a fix for this issue?
Specs:
Windows 11 Version 10.0.26100 Build 26100
Latest AMD Drivers 25.3.1 fresh install 8bit colors and freesync enabled (I think same problem with earlier drivers also)
Asus TUF B660 Plus Wifi D4 Motherboard
14600kf (also same problem with 12100f cpu)
Asus Dual RX6600 8GB
16GB 3200Mhz ram
650W Gold Seasonic psu
Kingston NV2 2TB
Asus VG279QM 280Hz Freesync monitor
I have tried many things including reinstalling drivers with ddu and disable Resizable bar but no fix.
