I have this exact same problem, with no texture packs at all. I've always played on this computer for so long, with almost no problems, except this. My computer definitely meets minimum requirements so it has to be something else. I've also tried fully reinstalling and trying different directories, which didn't work. The stranger thing is, this issue has come and gone before, only lasting a day before it went back to normal and I could play. But I'm researching it more now because it's the 2nd day this time and the issue is still here. I know this report is getting slightly old but if I made a bug report it would be flagged as a duplicate to this or another similar issue.
