[Amddefector]

What's a good program to test a GPU that I have just give a clean and replaced thermal paste please?

-The actual games you're going to play.
-Unigine Heaven: No DX12 support. Unigine Superposition has DX12, but it and the stress test are locked behind a paywall.
-Asus Realebench v2.5.6: It's a bit dated though; hasn't been updated in like 2-3 years.
-Aida64: Limited trial period - everything pretty much locked behind a paywall.
-Furmark: This one is like Prime95 for gpus, and only really useful for testing how good your gpu and chassis cooling is.

There's no one fits all here.
