Issues unresolved

Crashing and/or freezing in Offline mode

This issue is not dependent on the graphics API used.^[11]

Stutter every 15 seconds caused by large Steam friend list

Not connected to latency, present even offline.

Workaround: Temporarily block all (or most of) your Steam friends (they will remain in the blocked category to unblock later). The less friends you have - the less frames are lost every 15 seconds.^[12]^[13]

Tested with the open beta of the game on a GTX 760. In the game options, there are three possible AA methods, with the third not being selectable for me. The DLSS .dll can be found in <path-to-game>/\Engine\Binaries\ThirdParty\NVIDIA\NGX\Win64.

In the beta, HDR looks extremely washed out, raised blacks and shadows, nothing reaches peak brightness. Contrast and saturation sliders did nothing. No engine.ini file is available to attempt a fix
