Specifically speaking World of Warcraft. Getting good frame rates in MacOS but there is a slight "shudder?" "glitch?" I don't exactly know what to call it. Every now and again it acts like it wants to lag for like a frame, then it's smooth again.
Tried Windows with OTB Bootcamp Drivers and it's worse and frames were a bit lower.
Today I finally installed the "Blue" August drivers, seems to be an improvement in FPS but the slight stumble is still there at times. Wife says it seems to be happening a little less.
Noticed, it's usually fine/minimal when the game is launched and over time it gets worse and worse. (I'm talking on the 3-5 hour time table)
Heat Soak? Memory Leak?
Brainstorming and searching online for similar experiences, but not finding much about gaming on the 2020 5k iMac at all.
Maybe it's something to do with the abysmal refresh rate of the 5k iMac display?
-Going to plug in my 4k MSI Gaming Monitor and see what happens there.
Maybe it's throttling?:
-I've played with this a bit, seems Apple put in the firmware to automatically throttle the CPU when the GPU gets loaded up, check out your clockspeed when you put your GPU under load, they drop to 3.4-3.8 GHz, Temperature doesn't matter, the CPU slows down every time the GPU is put under heavy load. CPU actually runs cooler because of the down-clocking when the GPU is put under heavy load. I was seeing Mid-High 80's when the GPU is loaded and GPU stays fairly reasonably hot (I was seeing 76-78*C) CPU will hit 95-100*C and throttle when no load is on the GPU.
Quite a disappointment, a 5-6 year old PC that wasn't even "Top Of The Line" when it was built runs smoother overall than a $3,100 iMac, which is way more powerful and well equipped on paper.
Side note, I am noticing this is the way forward with 10th gen Intel Chips. I just built a desktop with the i9 in it, and it runs balls out until it throttles itself. I am assuming Apple is allowing this to some degree as well on the 10th gen chips.
Does anyone else notice any glitches, slight pauses while retaining high/acceptable frame rates?
