Factorio Forums

Odd bug that has shown up recently for me. I played through the campaign with no issues graphically, but as soon as I moved to single player my screen started tearing so badly I couldn't play. Yes, I turned vsync on in game, and yes I turned vsync on in the nvidia control panel, and neither of them did a thing. Odd thing is when I play windowed the problem goes away.

Also, when I play fullscreen there is a great deal of input lag for every action I do, but not in windowed mode.

On top of it all, I get around 32 fps in fullscreen, but immediately jump to a constant 60 fps as soon as I go windowed. Any ideas?

Specs:
Geforce GTX 965M
Intel I7-4710MQ
Windows 10

Please post a log file (factorio-current.log). You can find it here:
%appdata%\Factorio (usually C:\Users\<username>\AppData\Roaming\Factorio)

It could be an Nvidia driver issue as several users have reported this problem (21308, 21780), going back to older drivers might fix the problem.

From the log it seems like it might not be using your GTX, and only using the Intel HD adapter?

It does use GTX card.

Does it still happen if you use --force-opengl launch option?

It seems that laptops with dual graphics technology should use driver packages provided by laptop vendor in order to work properly.

Using the force openGL command solved everything, thank you very much!

Juuuuuuust kidding, game runs at 60fps now, but the tearing has now returned in a new form, now being a diagonal strip from the top left. neato
