Thank you all for your support to get me acquainted with ZorinOS the past few months. You're awesome!
I was playing Star Craft 2 this morning, when while in-game, the screen froze. Zeratul still responded when I clicked (though i don't know where), but there was no movement on the screen itself, nor would the screen scroll. Is this a RAM issue? I feel like this might be a RAM issue, maybe a Heroic Launcher issue?
And how much RAM does Your System have? And how fast is it? Is in BIOS the XMP Profile active? Have You checked the Logs for any Errors when the Game freezed?
The OP is running an Asus ProArt StudioBook system...
(1) 9th gen Intel Core I7-9750H 2.2GHZ 6-Core CPU.
(2) 64GB of RAM
(3) Quadro T2000 GPU with 4GB VRAM
(4) Disk Capacity 2.5TB
(5) Zorin OS 17.3 PRO
(6) Running in X11
It appears to me, that the OP's system exceeds the system requirements, by a whole lot.
The Quadro GPU cards are Nvidia's workstation GPU offering. While typically not meant for gaming, should be able to handle powering up old games like Star Craft 2, which have Windows 7 era of system requirements.
I'd suspect there is a driver for his Quadro in Additional Drivers.
What I could find out, the Quadro T2000 is between the GTX1650 and GTX1060 in performance, but as I mentioned, I've StarCrafted with it on both Windoze 10 and ZorinOS without problem.
