So when you unpack multimc from the zip file it generates a main folder. that main folder holds all the different instances of minecraft you might be running with multimc. Those instance folders have the saves and the NEI save files. I’ve already deleted that MultiMC folder and unpacked a fresh one. In that fresh MultiMC I’ve opened a fresh instance of bear’s pack for gt6 and gt1.
Both, even with a fresh reinstall, suffer from the same debilitating graphics issues.
I’ve reinstalled the nvidia drivers for my GPU before and nothing. It got better when I deleted the caches for Nvidia. Then I tried to clear it all out using a dedicated Display Drive Uninstaller and the problems came back. It’s clear that it’s a problem with the drivers themselves. But I’m really not sure where to go from here. This is probably outside the scope of what you can help me out with.
I’ve gotten the suggestion to downgrade drivers and I will post an update about how that turns out.
