DXVK v2.5.2 causes very unstable and choppy framerate.
Games: C&C Red Alert 2
StarCraft 2
Also, from version 2.5, DXVK no longer works on C&C Tiberian Sun.

CPU: AMD Ryzen 9 3950X 16-Core Processor 3.49 GHz
GPU: AMD Radeon VII

That game uses ddraw6 by default, and would have never worked with DXVK, unless you use some kind of mod?

I'm using CNC TS Client 7.01, and I switch the render to the CNC-DDRAW.

C&C Red Alert 2 is also a ddraw game. I'm assuming you're using cnc-ddraw's d3d9 renderer for that as well? Note that cnc-ddraw has an opengl backend and you should be using that directly for better performance anyway.

Try setting: renderer=opengl in ddraw.ini.

from version 2.5, DXVK no longer works on C&C Tiberian Sun.

Seems fine here, even with cnc-ddraw d3d9 + dxvk, not sure what the problem is on your end.

Choppy FPS fixed, by switching on the Radeon Enhanced Sync of AMD video cards in the driver.

@quake1982 Does this also work fine with 2.5.3 if you make a file called dxvk.conf next to the exe and insert dxvk.allowFse = True ?

Thank you for the reply, the latest version works fine for the game that I mentioned. But, I'll try the way you provided. Version 2.5.2 with choppy fps was quite strange on my PC, the major issue was because of the driver of my AMD card. The Radeon 7 is a pretty old video card comparing the RX 6000 series.
