I've been having the same issue, but I have an AMD card (R9 380 4G) with up-to-date drivers (in fact, I've updated them 3 times since this first started happening nearly a month ago, and it has yet to fix anything). Java and Windows 10 were then and are currently also up-to-date.

Here's a link of my log:


I'll give it a go without Optifine and see what happens (it's probably out of date, anyways).

If I still have the same problem after that, I'll start a seperate thread for my issue.

*Edit: Yep, Optifine was the culprit on my end, thanks for that advice.
