The shader compile is likely a red herring, since all shaders ought to be compiled at first launch of the game, or when you have a new driver.
Not all shaders are compiled at launch. They are compiled during gameplay too!
If you have more information how the shader cache works on Windows, I'd gladly read. I'm sure the cache will be limited though, so if you play some other games in between, the cache will be deleted. The shader compilations during gameplay also means it will take a long time of playing until all shaders are loaded into the cache.
Are you sure?
My experience with the game is that on your first launch, for the first 5 - 10 minutes of playing the game will be compiling all shaders. That is to say, it doesn't prevent you from playing while compiling shaders but it does make sure to compile all of them

Yes, of course I'm sure.
Did you read my other messages?
In dxvk you can have the HUD show you when shaders are compiled, also I've been diving into the source code to check if I can optimize something in this step, but the respective code seems alright. There is another fork which will ignore drawing stuff which isn't compiled yet, but that's against the d3d spec.

A little bit late, but i was in the same boat. Every other game runs fine, i reinstalled windows, tried different bios settings, nothign worked. In the end i found out that i only have these performance problems when using my 5070 ti. I swapped to a 4060 ti and stutters were gone. I thought its probably a blackwell thing, but when testing with a 5060, there were also no stutters. Since every single other game runs flawlessly, i assume my 5070 ti is not broken and ow2 might have a software/driver problem with 5070 Tis? Though that seems unlikly to me well. Im yet to find another overwatch player with a rtx 5070 ti who could do a benchmark.
