Sudden drop in framerate after playing for a while

[Crimson13]

So after a couple of playthroughs I noticed that after a good half-hour/hour of playing I'd start to get lag. The one thing I noticed though was that it only happened outside, if I went into any interior Skyrim would go back to playing smooth. I checked via FRAPS and oddly enough it seemed like it happened in layers. My game would start and stay right around 60fps give or take, then after a half-hour/hour it would drop to 30, and then it would go to 20 shorty after. And they would generally stay within those numbers until the next drop happened and then be stable until it does the same thing again.

 

What stands out for me is that I started to notice a pattern in when the drops happened, I'd have the 60fps and I would enter into a building and come back out with 30fps. The same happens again and goes to 20fps. And the frame rate would only shoot down outside, inside I had 60fps. I'm not even sure if it's time based due to the 'fps fine, enter interior, exit to exterior, fps falls' way it seems to go.

 

Would anyone know why this is happening the way it is?

Well first things first.

Odd issue you have there.

1. Are you using the alpha version of SKSE (with MEMPatch)?

2. What are your uGridsToLoad setting?

3. Have you tried making a new saved game to see if you can reproduce the issue there (since if you can't uit;ll mean your save is messed up because you added and took away to many mods mid playthrough)

1.Still using the 1.6.16 version of SKSE, I'm using the modified SKES.ini and SSME.

2. I haven't touched uGridToLoad, the only thing I have that's related to it is Stable uGridToLoad.

3. I haven't done that yet, when I get done with work today I'll have more time to see if it's something like that. For taking away mods the only mods I took away from my current playthrough are Enchanting Freedom (Which I replaced with No Enchantment Restrictions) and RCRN (Which I replaced with Climates of Tamriel and it's patches.).

If those were the mods you removed the I'd definitely say you need to at least try a new game.
