Hi all, I have an interesting issue in Skyrim. Everytime I am in wide areas (usualls with fog or fires nearby), my framerate drops to constant 29.9 fps. This especially applied to Markarth when standing with my back to the castle and lookig over the city (see screenshots on the bottom). Everywhere else I can play with constant 60fps with a few drops to the 40-50s in large combats. In normal areas, I use between 70-100% GPU load, 1900-2000MB VRAM and up to 50% CPU (2 Cores out of 4). I am using MSI afterburner to monitor GPU usage: GPU load in the critical 29.9 fps areas is around 60% and VRAM is at 1900MB out of 2048MB. Therefore I can exclude a GPU bottleneck. CPU load is at ~25% which should be no bottleneck as well because Skyrim can use 2 Cores. MSI on screen display is used for fps monitoring. For eliminating the skyrim micro stuttering I use windowed mode with simple borderless window (SBW.exe). SKSE is running as well. My settings are all maxed out (except MSAA 4x instead of 8x) and I am using a bunch of graphics modifications and ini tweaks: My number of mods is between 40-50:

My hardware is the following: Intel i5 2500k @ 4,5Ghz Gigabyte Radeon hd7870 @ 1230/5800 16GB RAM Win7 64bit To my opinion, 29.9 fps looks very ugly and are almost implayable (input lag etc) so I would be very happy if there is someone who can help me with this problem. I have already searched in many forums but I have not been able to find someone with similiar problems. Thank you very much in advance. Edit: If anyone wants to reproduce my issue he is very welcome to do so. Please be aware that for reproducing the error setting ugridstoload to 7 and adjusting preloadsizelimit, uinteriorcellbuffer and uexteriorcellbuffer might be necessary! Here are screenshots of critical locations for me: Dropbox link to my screenshots 2013-02-05_00009.jpg (27% COU load, 45% GPU load, 1900MB VRAM) ScreenShot2.jpg (20% CPU, 40% GPU, 1900MB VRAM) ScreenShot3.jpg (24% CPU, 63% GPU, 1950 MB VRAM) (the other screenshots in the zip folder are just for fun. Although taken in wide areas I had not the 29.9 fps issue there. Making these, I had 50-60fps with 100% GPU load)
