The game periodically (and completely randomly) can 'freeze' my PC. I will list the spec below:
CPU: Intel I9 9900K (watercooled, not OC'd)
GPU: MSI RTX 2080ti 11GB Ventus
SSD: Samsung 970 EVO Plus V-NAND M.2 500GB SSD (Windows 10, 3dx installed)
RAM: 32GB DDR4 Corsair Vengeance LPX 3000MHz
As you can see, this is massively overkill for a game like 3dx (I play other games eg. Modern Warfare, Destiny 2, WoW, GTA V). All the games I mentioned are playable on Ultra Sett
