Hi guys. Been having some trouble quite lately with Minecraft after playing for a certain amount of time. After about 5-10 minutes of playing (this varies sometimes, and has been dropping to shorter times), my game starts to get huge lag spikes. Some lasting for more than 30 seconds at a time. When this happens, I tab out and look at the "Performance" tab on task manager. Looking at the CPU usage, it's usually around 90% - 100%. I've already tried Googling some answers, reinstalling Java and Minecraft, and deleting my .minecraft folder, unfortunately, none have worked.

I do have some mods loaded, also. They are Rei's Minimap, MAtmos Sounds, OptiFine, InventoryTweaks, and Shibby's FlyMod.
Thanks!
Mods.
Remove then with a force update and see if it still happens.
P.s. This section is for unmodified clients
Probably should've specified this still happened without mods, as well.

Yeah you're computer is not able to handle that. If you want stable FPS, use normal.
