I applied first step from the instructions above and deleted dgpu main kext, but left the display kext in the place. There are 2 kexts in Mac OS fo r 370, one is responsible for the card, another one is responsible for the lcd display ( not mentioned in this article). In this article there are 3 steps how to disable dgpu completely. Also i forgot to say - i’m using Vulkan api ( tight click on the game and choose manage - dlc)Ģ.I found few possible solutions for this. Unless built in LCD will be accelerated from m2 gpu. I tested in many ways and my thoughts that if d gpu will be completely disabled you won't get more then 60 fps in any app or game. In game go to hero demo mode, after check the exclusive mode and resolution one more time (exclusive mode can be turned off). (Use only exclusive mode and don't open desktop while test - gpu can switch to dicrete mode during this). Case is the same on Catalina and high Sierra. And it doesn't even matter if you rx580 is connected or not.

I'm not sure if it's only on my machine but I see this cursor with artifacts only when display is accelerated by the igpu. However, the iGPU is used for h264 hardware acceleration so when I play a h264 video file, the Intel Iris Pro will be used to decode the file even if the laptop is in clamshell mode. Intel Iris Pro generally stays idle when used with external monitor connected directly to the RX 580. I guess the game demands for CPU processing power as well. The GPU history chart confirmed that only the RX 580 was used although both internal fans were running at high rpm throughout the game. I was surprised that the RX 580 could handle the game at 5K. With Dota 2 at high settings, I got about 60-70fps at 2560 x 1440 and about 20-30fps at 5120 x 2880. I also carried out another test using an external 5K monitor connected to the RX 580. How did you manage to force the game to use the RX 580 without any external display connected to the RX 580? I carried out this test using the internal LCD only. I installed Dota 2 (since it is free) but the game seems to only utilise either the Intel Iris Pro (forced Integrated mode via gfxCardStatus) or the M370X (forced discreet only or dynamic switching mode). Can you please confirm that both of your tests were carried out using the internal LCD only?
