What frequency are you running your Ryzen 1800x at?
I am running the 2700X at a constant 4.3 GHz.
The CPU speed will likely dominate performance at such low resolutions.
I will drop teh CPU frequency to 3.6GHz and see how much the FPS drops to on the RX Vega 64 Liquid next.
Dropping the frequency of the 2700X from 4.3GHz down to 3.6GHz dropped the CSGO FPS from FPS = 362 to FPS=347.
I will reluctantly (I hate the GUI/UI and it has been unstable so far) install Adrenalin 2020 20.2.2 and see how it performs on CSGO next.
Right here goes.
I have run DDU and performed Factory Reset install of Adrenalin 2020.
Here are the screenshots of this awful, messy, badly layed out and hard to use interface.
Performance Tuning - which I just noticed does not understand 0.5% GPU overclock on the performance slider when loaded from Adrenalin 2019 Profile:
Adrenalin 2020 GUI delenda est.
Adrenalin 2020 20.2.2 seems to be giving me slightly lower performance and I do not believe the GPU1 SCLK numbers.
Here is the result of running CSGO on the RX Vega 64 Liquid with Adrenalin 2020 20.2.2.
It is slightly lower at about 356 FPS is you believe the Radeon Performance overlay or 353 FPS if you believe Steam FPS counter.
They do not match despite using fastest polling rate.
The Radeon Performance Overlay Custom location would not work at all.
I was unable to display the overlay in the Top RHS or Bottom RHS of the screen.
The Adrenalin 2020 GUI/UI is a total pain to use.
Here are the settings used:
Here are the reported FPS numbers from the Always On Game Advisor it is reporting only 112.1 FPS...
I just noticed that I had FXAA enabled for some reason for the RX Vega 64 Liquid with Adrenalin 19.12.1.
This will reduce performance by a few FPS for these settings.
Since there is NO WAY I am putting up with the Adrenalin 2020 GUI/UI - I will uninstall it and reinstall Adrenalin 2019 19.12.1 and report the difference in FPS by running with FXAA off.
FXAA off = about the same performance as FXAA on in Adrenalin 2019 19.12.1.
Here is a working Game Advisor Result:
I can run the game at 4K with similar performance...
RE: It may be that Nvidia cards run CSGO better in DX11 because they have a Multithreaded DX11 driver.
Except that CSGO is DirectX 9 ...
Interesting that the AMD XFX RX Vega 64 Liquid can beat a Palit RTX2080 OC on this DirectX 9 game based on my attempt so far.
The RX Vega 64 Liquid has been undervolted and overclocked, especially the HBM2 memory.
I will go back and take a look at overclocking the RTX 2080 OC later, but for now, AMD is winning hands down...
Yes I have tried max_fps 0, max_fps 300 etc.
I checked if there was a max_fps limiter in the game engine.
