I’m trying to debug a shader compile hitch in my game. I’m prewarming all my shaders, so there must be some rogue shader(s) that I missed during the prewarm phase.
Is there a simple way to clear the compiled shaders for a player build? One which doesn’t involve running the build on a new PC, reinstalling graphics drivers, etc.?
I’m going to use “Log Shader Compilation” after to catch the shader that causes the hitch–in theory. I haven’t actually used it before; looks like it’s a solution though.
Which graphics API are you running this on?
Windows 10 - DirectX 11 and 12.
I was deleting the shader cache in the project folder in order to reproduce the problem in the editor; it could be time-consuming compiling every shader again though.
I managed to figure out what was causing the hitch: post-processing shaders. I have an exorbitant amount of custom post effects.
My fix is to activate the player camera a little bit before the load screen is removed. Everything is smooth as silk now.
I not sure how removing the compiled variant cache could’ve helped you here. Yes, it can be time-consuming, that’s why we have the cache in the first place
