#AMD ADRENALIN CROSSFIRE HOW TO#
If you want to keep the Adrenalin 19.12.1 User Interface but install the Adrenalin 2020 20.12.1 drivers I will tell you how to do that later.Ĭougar MX310 MidiTower ATX Case, main side is openĬrucial Ballastix BL8G36C16U4B (2 pcs., XMPII Mode)ĪSRock Radeon RX 570 8GB (In top PCIe x16 slot) If that works and you are happy with it, then fine.
Install Adrenalin 2019 19.12.1 and see if Crossfire performance is o.k. You could use that interface to get the CrossFire interface but run with 2020 20.12.1 Drivers - a Hybrid Driver install.ġ1. 19.12.1 Driver using the better QT based GUI/UI still has full Crossfire Support. I think I have a copy of Project Cars 2 somewhere - I will check.ĩ. I could take a look at DX11 Crossfire easily on a pair of R9 Fury X on an i7-4790K PC if you really want. Some Nvidia Gameworks options such as Godrays cause problems with DX11 Crossfire.Ĩ. In other words, if primary GPU Utilization is high (90-100%) then turning DX11 Crossfire on should help performance on supported games at higher resolutions and visual quality settings.
#AMD ADRENALIN CROSSFIRE 1080P#
You will see more benefit in DX11 Crossfire going from 1080p -> 2K -> 4K resolution.ħ. Often games are limited by CPU at 1080p, not the GPU.Ħ. If you run a game at 1080p and turn on DX11 Crossfire, you may well get a lower framerate because the CPU is loaded due to Crossfire overhead. One thing you need to account for is turning DX11 Crossfire on incurs a processor overhead. That game has DX12 though, and DX12 MultiGPU still worked fine.ĥ.
Last time I tested it it was completely broken, with visual corruption. DX11 Crossfire used to work great on a pair of RX Vega 64 Liquid GPU. That means updates / modifications to games that may cause problems for DX11 Crossfire will not get fixed. AMD dropped all support for DX11 Crossfire issues on games a long time ago.Ĥ. If you look there is no selection of Which GPU to pair or DX11 Crossfire Profiles.ģ. Adrenalin 2020 support for DX12 MultiGPU / DX11 CrossFire is pants. Is it an operating system's bug, or is it a driver's bug, or is it game developers changing their game engine suddenly (can not imagine it really).Ģ. I saw many videos in YouTube showing working CrossFire in GTA V and Project Cars 2, so this makes me think that something is wrong somewhere, I do not know yet where. GTA V does not use the second GPU at all, Project Cars 2 tries to use it, but the second card is cold and its GPU load is very weak and episodical. This is very strange.īoth cards are in PCIe x8 3.0 mode, as GPU-Z shows. enabled using the default mode, while the single card mode (C.F. GTA V is not using the second card in any possible C.F.
#AMD ADRENALIN CROSSFIRE 64 BIT#
is Windows 10 64 bit Professional with all latest patches.Īll DirectX libraries, games and so on are up to date.ĬrossFire mode was tested by me in 3DMark using all possible CrossFire modes and it really doubles the framerate in the Time Spy test. Graphic cards: dual AMD Radeon RX 570 8GB. Video card driver is the latest stable - 20.11.2. I have problems with AMD CrossFire in games.
