Have you attempted adjusting the RAM capacity to a larger value? The software typically operates with a default limit of 512M, but consider modifying it to something such as 2048M.
I'm facing the same problem too. My system has a 1080 ti with 32 gb of RAM, but it experiences strange frame drops when Optimize is turned on.
I'm using the newest Optifine version. Playing without it made things worse.
Sure, I can provide the version details of the game you're playing and OptiFine. You mentioned you recently received a 580, so I'll note that. Also, let me know if you'd like information about how it behaves on an older version.
I've been experiencing the same problem. After adjusting the settings, I noticed VSync remained active. Turning it off improved performance significantly, though FPS fluctuations persist. It's not yet affecting gameplay.
