Stock base iMac Pro and game from Apple store. Was slow to use seed/swap devices but ok in windowed mode. Tried fullscreen and it's glourious to look at but now stalls, freezes runs slow. Cannot get it back into window mode. Cannot believe that with this much power a game like this brings my new baby to it's knees?? Once it started making noise !!! First time I have heard the fans . Put my hand behind to feel the air comming out and it was real warm. Switched to finder and wait and the fans did spin down. How in the world can this play a first person shooter type game ?? Is something wrong with mine or is this normal??

BTW old mach is a dual G-4 bought on 03/02/2002 still runs :) 10.2/OS9

Which settings are you running this game under, and do you have VSync activated?

Char shadow off
Audio qual high
size 2560x1440
screen set windowed *
V Sync off
Quality preset low
all else on that list is set to med
texture memory 50%
Resolution scale 106
field of view 94
motion blur .246
Invert Y axis off
trans type smooth
free roam
node vis middle

*was playing in a window switched to fullscreen cannot get it back to a window
Think most of this is the default as I don't know what most of this actually means.
E-mailed the DEV and was told to ask here, "game not tested on such a new machine"???
TIA

Turn on VSync and try again :) Should work wonders regarding the temperature in your iMac!

Thanks I had tried that before but often changes made in settings do not really change every time. I made V-sync on to stay , and this really helps.
Activity monitor shows game using 5-6 G of ram. Any way to put the whole game in ram?? This would help with the pauses I think. In the old days you could make a ram disk, any way to do that now??

I guess you‘d need to install a program to create a RAM disk and install the game there every time you reboot the machine - not worth it IMHO.

My guess is either:
Not fully optimized graphics drivers, and/or
Sub-optimal port of the game. (Since it's in the app store I'm guessing it's native, but for an example of just how bad it can be, The Witcher's Mac version was basically the Windows game bundled with Wine... which isn't a Mac version at all.) Probably not much to do but to wait for operating system updates and game patches.
