In GZDoom, try this command:
- Code: Select all • Expand view
bench
should create a text file in your GZDoom directory called benchmark.txt
It is suggested to run this through a bound key rather than through the console, but, it should still give you some information you may be looking for.
Please note that you didn’t explain much in your post, so if my answer isn’t helpful it is only because I have little information from you on what exactly you’re wanting.
