Hi, Welcome to the forums…
Please can you include your DXdiag export to provide more information on your specific setup.
The player.log file is showing the usual debug information and game engine errors etc but its not showing total crashes. Usually there are much more defined logs saying what crashed and providing details of the error.log the game generates when its a game engine crash…
The lack of logs basically means that your system is crashing before the game engine can actually log any possible problems. This is usually a sign that the crash is happening due to driver issues, physical issues (like overheating/power), some sort of corruption in system files or game files or even a conflict with something else installed on your system.
The dxdiag diagnostics might have info to work from and you can “View Reliability History” on your system to see if Windows itself managed to log what is happening to at least point in the correct direction to troubleshoot this.
The in-game settings you are using should mean that the crashes are not being caused by the known performance related instability. i.e. using settings too high for your hardware is known to cause crashes…
Your description of the game running for a while and then crashing could be hardware related so I would advise you to monitor your system while playing - CPU, GPU, Memory etc… and see if there is something that is maxing out, overheating, drawing too much power etc. Something like HWmonitor logging results could be useful.
It could also be something running periodically in background that might not be system intensive, but conflicts with the Unity game engine and crashes your system…
If could also obviously be a problem with the game itself… It is in beta so things like this can happen and your very specific combination of hardware and the game might be highlighting a bug - unfortunately this is very hard to troubleshoot… So, to figure out if it may be something like this, is there any common element that you are doing when the crashing tends to happen? Are you loading into a map, using a specific character, using a specific skill? doing a specific thing in LE?
Please post your dxdiag output and we can see if there is anything that will help narrow the focus to find the issue.
