fcpX glitch issues - iGpu+Nvidia dGpu power management

[mariosk9gr]

Hi everyone! Since High Sierra, I have very bad experience with FCPX 10.4 in terms of performance. Video editing process is a nightmare because its very slow and the renderings are slower than a 5 year old MacBook Pro. In that moment I want to mention that all these years I'm using my Nvidia GPU only, and the iGPU is always disabled.

After spending many hours to find a solution to my problem, I discovered a guide on the Internet (https://hackintosher.com/guides/fix-rendering-issues-fcpx-high-sierra/) that is suggesting to turn on iGPU and enable "hardware encoding supported" on my iGPU. I followed the instructions and I found that FCPX was much much faster than before. On the ACPI column in Clover Configurator the guide was suggesting to use 3 patches but only the 2 were listed, so I added the 3rd one "change PEGP to GFX0" and saved. When I open the the same column, the 3rd patch isn't listed but it shows normally if I open the config.plist with text. 

My problem in FCPX lies that, every time I will use transitions, effects, stabilizer, I get as a result serious glitch (green square patterns) effects! I tried also BruceX 5kK, and it took 45 secs to render. As a result I was having again green squares full of artifacts. Geekbench from the other gives very good scores with both iGpu and dGpu. I hope there is a solution to my problem, any suggestions?

My System is:
Intel i7 4790k
16GB DDR3 2400mhz (Dual Channel) 11-13-13-31
Asus Z97-P
Asus GTX 770 2GB
Samsung 850 EVO 250GB (10.3.3 main disk)
Samsung 840 EVO 250GB (10.3.3 test disk)
Dell U2413 (1920x1200) mDP connection
Dell U2417H (1920x1080) HDMI connection
SMBIOS is iMac 14.2

Hi, I experienced similar graphic issues while I had my iGPU (Intel i5 + Gigabyte Z97H) enabled together with an GTX 1050 Ti.
After I disabled the iGPU in the BIOS everything looks and works good. I can't tell about graphics performance though.

Hi Ron, exactly when you disable from bios the integrated gpu everything works ok.

Actually the problem appears only with fcpx and that is because it uses igpu more than the dedicated one.It renders faster and the whole workflow is going faster actually.

Also since High Sierra, nvidia web drivers cause a lot of issues.I hope a good working stable release will come out soon from nvidia...
