It happens even with regular D3D under the right conditions. What you're describing and looking at it simply what happens when game isn't in focus. I've managed to record an apitrace eventually: Log files I followed the instructions posted on Wiki, don't know what else I can do to obtain an apitrace file. And yes, I've reinstalled Visual C++ Redistributable for Visual Studio 2015, both x86 and 圆4 versions. It says MSVCP140D.dll, VCRUNTIME140D.dll and UCRTBASED.DLL are not found. Unfortunately I cannot generate apitrace. DXVK version: Latest from Actions (branch master) ->.Game: Grand Theft Auto IV: The Complete Edition v1.2.0.43.It's easy to figure out when the game decides to stop given that it takes way more time than regular loading screen. Usually loading screens take a few seconds, like 3-5 seconds, but when the game decides to crash/freeze, it will stay longer, like ~10 seconds. GTA IV runs smoothly with DXVK, but sometimes it will crash/freeze after going on a mission, during the loading screen.
