Framerate drop/slow down in G&K

[The_Commandant]

I've been having this problem ever since I downloaded G&K five or six months ago. I'll play for 5 or so minutes before I start getting slowdown every 60 seconds or so. It's never enough to be completely crippling, but it is noticeable; frame rate drops, simulating other players' moves takes longer, the delay between clicking on a city and the city screen coming up is longer. Essentially, everything is just bogged down and slow for about 20-30 seconds. Then it'll just pop back to normal and be fine for another minute or two.

I play it on DirectX 10/11. Processor is an Intel i7-3610QM @ 2.3 GHz. 8 GB DDR3 RAM, nVidiea GeForce GT 650M w/ 2GB memory. Specs are not an issue. I previously (pre G&K) played on the highest settings without a problem. Lowering all the graphical settings to as low as they can go hasn't helped.

Anyone have any workarounds/tips?

I'm having a similar issue. After an half hour or so, the game slows down to a level where the game is not playable. However, this just cropped up today. I have never had this issue before now. Have G&K and all DLC's. The game played fine before on high settings, running in DX 10/11 mode.

PC Specs:
Intel Core i5-3210M CPU, 8 GB RAM, Intel HD 4000 graphics.

I will try to lower the graphics and see if that helps.

Edit: Lowering all setting to medium did not help. The slowdown occurred within 10 minutes!

Edit 2: OK, now it seems to be working fine. Make up your mind, Civ5!

I have the same problem (I play alone). I save the game and go back. It starts out fine again. I was wondering if this might not be an internet/steam issue. I meet all requirements above minimum and have all graphics at low,fog of war at medium.
