Hm, that is annoying! I've got some things that might help:
- Are you running any programs in the background, while running TEF? Having music or an internet browser running can greatly impact on framerate. Even if you don't think this is an issue, check that your computer isn't doing this on its own, automatically installing updates or something like that.

- Have you made any software changes to your computer recently that might have caused this? Updated any graphics drivers ect...if you have you could try reverting to the last version you used before this issue arose.

- Is your internet connection still running at the same strength? If you use a router and wireless, check your connection strength. Sometimes multiple people using the internet at once can slow it down, so try connecting at different time/when others on your network are offline.

That's really all I can come up with for now, hopefully this issue can be fixed. Sometimes TEF magically likes to cause and fix problems...like it gets bored or something. :[

I had that the past two days and had to perform a "system restore" on my computer to fix it.

Darn! Still GlobalBeauty is right, a system restore should defiantly fix this if the problem is anything on your end.

I used to have this glitch! :0 Try going to display in the esc. menu, go to the bottom where all the sliders are, and change 'nature detail' to around 50%. If that still doesn't help to solve things, then try changing the 'soft effect'. These are the things that helped me with my forest glitches, and made things look like I was in a dream. But it worked for me. I hope it works for you..? :J

Can someone help me, I cant download the TEF 3.31 because this message pops up saying ''?SerContextRenderCountName@A3d_Channel@@UAEXPAD@Z could not be located in the dynamic link library HighPoly.dll. I tried unistalling then downloading again nothing worked please help me.
