Mac High Sierra FPS Issues With Graphic Card

​First of all I would like to apologize to riot. I have sent in alot of bug reports in the past few hours and days raging about FPS issues. I am like 95% sure that there is some issue with either my Graphic Card, or the Graphic Cards on High Sierra.

So My sister just got a new MacBook Pro the same type as me (15 inch Mid 2015), but hers does not have a dedicated graphic card. I switched out my Hard Drive and put it in her machine and got 60 fps on Max Settings, while on low settings I would get 2-15 fps on my computer with the graphic card.

Below I will list the specs of each computer.

Both computers are running Mac OS High Sierra [Version 10.13 Beta (17A306f)] Mine (FPS Issues)

  • Intel i7 2.5 GHz
  • 16 GB Ram
  • Intel Iris Pro Graphics
  • AMD Radeon R9 M370X Sisters (League runs perfectly)
  • Intel i7 2.2 GHz
  • 16 GB Ram
  • Intel Iris Pro Graphics

So the only (real) difference between the two computers would be my laptop has a dedicated graphic card. There may be something wonky with High Sierra and graphics so I will report this to apple as well.

Hope you can use this information to debug any issues, and I am sorry for raging earlier today/this week. <3

Riot if you would like me to run the Hextech tool on both computers I would be willing to, just say the word.

I have the same issue with the FPS Drop. With Sierra I had every time 60Fps and everything was super smooth.

Now with High Sierra I got 30 - 40 FPS... Thats not smooth at all..

Riot pls fix.

FYI: I ran the Apple Hardware Test, and it did NOT come up that my graphic card was broken. It still could be some driver issue with Mac OS High Sierra.

my problem is like yours. My right click is always behind maybe 0.5 sec 0r 1/4 sec .. I checked my ping .. is like always.. 27 ms .. before I install high Sierra my MacBook Pro was a rocket for league I played with 80-120 fps.. but I play with 60 fps now .. I don't know where is the problem.. maybe we get a better client from riot .. from apple we don't get a gamer Operating System..

Have you ever had a client crash? The client crashed many times after update High Sierra. Is there anyone who can explain the reason and help me?
