For almost 4 years now (not continuous), My Roblox client has had a problem with freezing up, and going to Not Responding, where the client cannot recover, and I have to rejoin.
However, the only solution was to use the FFlagDebugGraphicsPreferD3D11FL10 FFlag, as described in this post I made a while ago (mind you, I didn’t know the FFlag name). Therefore, I request that FFlagDebugGraphicsPreferD3D11FL10 is put on the FFlag allowlist
I’m not fully sure if this FFlag exists anymore, or has been already denied from the allowlist, so this is my last hope; otherwise, I guess the only solution is to upgrade PCs (which doesn’t seem to be happening in the near future)
