[0.12.6] Unexpected Error Occured

[zakthefallen]

I've been playing Factorio 12.6 for hours now, and it was great until just now. After a couple minutes of playing the game, it crashes. I get an error popup telling me about it, but the game does this EVERY time I load it. It doesn't matter if I start a new game, it even does this without mods.

I was playing this version with Bob's Mods just fine for several hours, then I decide to disable those mods and start a new game.

Before this, I did rarely get a game freeze, but nothing that happened frequently. Here's the error log:

Stack trace in your log says it crashed somewhere deep in nVidia driver (nvd3dumx.dll), so I don't know how to help you. Maybe try to reboot your computer.

It turns out that lowering the graphics settings fixed the crash completely. Strange how it ran Factorio for hours with a big tech mod, then suddenly had a problem when I REMOVED the mods and was playing the vanilla game.

I did notice that by default the setting for Video Memory Usage was set to 'All'. I changed that to 'Max', then dropped graphics quality down to 'Low'.

As a nice side-effect, the rare bits of lag I encountered are gone now. Haven't tried it with Bob's Mods enabled, but it's running better than before, that's for sure
