Hi all,

About 6 months ago, I built a computer with the following specs:

AMD FX-6300
NVIDIA Geforce GTX 770
8GB of Team Vulcan Memory
ASUS M5A97 R2.0 Motherboard
Samsung 840 EVO 120GB SSD
500GB WD Blue HD
Windows 7 Home Premium

When I first built it, Minecraft ran at full settings with ease. 150+ fps I even threw super intense texture packs and shaders at it and it worked fine. Just a month or so ago, I downloaded Windows 8.1. Since then, Minecraft hasn't been running as well. Not even close, really. I run it without any textures or shaders at max settings and I get SERIOUS fps dips. The lag is just insane. Does anybody know why this might be? I tried dedicating more RAM towards it but it won't even open if I do that. The computer runs all other games with ease at full settings.

HELP!!!!!!!!!!!

With the latest Minecraft updates more issues come along and more lag spikes, it's probably Mojang's fault but anyway if you want to fix these lag spikes it's probably a good idea to install Optifine ( Http://optifine.net ) and closing all unused programs and maybe allocating some more RAM, however there is possibly another reason; Minecraft ONLY uses one core and with AMD CPUs I'd highly reccomend Optifine and using Multi-Core chunk loading.

I'm assuming you've already tried optifine and tinkering with the graphics settings (both minecraft and NVIDIA control panel), and that all drivers are up to date (especially the graphics drivers). If the driver is causing issues, try disabling driver signature enforcement and/or secure boot. Windows 8 and 8.1 cause alot of problems with newer, unsigned beta drivers. Are you OCed? Fresh install of minecraft? 64-bit Java? Mods?

Could be that you need to install/re-install Java. Make sure you uninstall ALL other versions first and you manually install 64-bit java if windows is 64-bit.
Minecraft is not as robust as it once was. I'm not sure if it's because of Minecraft or Java. It's a shame, really. It's a business now.
