Re: Crysis 3 low FPS drops & low GPU utilization with RX 480

Sorry for the delay but the last set of videos took a long time to process. 
I ran a ~ 27 minute recording to show AMD how an old GTX780Ti and old i7-4770K CPU beat performance of:

R9 Fury X on i7-4790K. 
RX Vega 64 Liquid on a Ryzen 2700X.

Moving to Windows 10 19.03 makes no difference I did a special install of Windows 10 19.03 yesterday and checked. 

Thanks.

Re: Crysis 3 low FPS drops & low GPU utilization with RX 480

Thank you very much colesdav

These are very helpful benchmarking captures! I really hope AMD Radeon will improve on these driver issues, very strange how certain games are showing flaws in their drivers, whereas a game like Battlefield 1 runs perfectly at 80-100FPS with DirectX 11 on Ultra settings with my computer.

I guess certain games use different graphics API function calls for the same thing to render; for example, lighting, etc. which are barely working for new-ish radeon graphics cards.

Kind regards

Jacques

I know DX9 is problematic in a few games and also slow.

I cant even run Catherine Classic on my AMD GPU I must use my intel gpu for that lol.

zinx‌ I do not know that game, but yes it is really sad!

It is not only DX9, it is OpenGl, DirectX 8, DirectX 9, DirecX 10, DirectX 11, even Direct X 12 (Hitman 2016) where it depends on the game for some reason.

With nvidia drivers performance seems to be more consistent, but with Radeon drivers it is a hit/miss for specific games.

Re: Crysis 3 low FPS drops & low GPU utilization with RX 480

BTW Did you try any games that use the Vulkan API?

I opened another thread here about V-sync issues that I get.

But I didnt try any game but mostly sotware/emulators.

If you know of any game that gets tearing issues with vsync can you respond in my thread?

Thanks..

This is the thread : https://community.amd.com/thread/240310 

I am talking only about the Windows driver and not the RADV driver on Linux which is fine with vsync.
