No freezes for me lately either. Philippe, did you turn your Anisotropic settings down? If so, has that helped? That seems to be one that causes the freezes on my system both on Linux and Windows. It's been rock-steady reliable for the past couple of weeks so I'm going to leave all settings well alone.
Pete, I have putting in 2 my anisotropic set, and I have changing my gpl install, I have putting on my SSD (on the advice of Axel)
to summarize, I have 2 modifications, I do not know which one has the most impact.
I leave everything as it is, it works well, I win races, lol
a big thank you to you and axel
