Hi,
unfortunately, I suffer from game freezes too. The first time the freezes occurred where in the small swamp area in the southwest corner of Artamark. A simple reboot solved the Problem. But since I arrived in the swamps, the game has become unplayable. The Game freezes every few minutes.
Before I reached the swamps, I could play without problems, even with activated weather and PhysX effects.
I have set the tool Glary Utilities 5 as described but it does not bring any improvements.
I have the Steam version
With newest Community patch
Trimmed elite textures
Enhanced Mod
No Fog Mod
Camera Tweak
