Severe FPS Drops The Elder Scrolls V: Skyrim

[Akshey]

I get severe FPS drops into the 1-5 range that last for 1-5 minutes every hour or so playing the game. My normal fps is around 40-60; it only drops during these moments. They seem to occur when i transition to a new area, only about 1/10th of the time. It also seems to happen when the game autosaves. After these FPS dropping moments, if I alt-ctrl-delete and bring up task manager, then retransition into the game, the game immediately fixes itself. However, this is an extremely annoying thing to have to do, break immersion, etc. Anyone else with this same problem, and is there a solution?

I am also having a recurring but not so often drop in frame rate only after entering an indoor location. Restarting the game resolves this but it has recurred every time I play so far for me but I am thinking of updating my current video card drivers and also trying your method to see if it works for me.) I have also crashed to desktop a few times, also i have seen things appear purple in color and shortly after a crash to the desktop. My entire skill screen was purple or pink once also). Also after crashing to the desktop i get a corrupt auto save but then i get the message from windows seven saying Skyrim stop working, It locks at this point forcing me to hit alt+ctrl+delete key to get out of it.

Mine seems to happen most often when i transition between completely different areas I have noticed. Like for instance I just traveled to whiterun and it did it. I've got an ATI HD 6850, newest drivers.

I'm having this issue as well; it's crazy, just occasionally it drops to a few FPS, seemingly for no reason. I was in a cave earlier and looking at some waterfalls slowed it right down, but killing the game and going back in, back at a steady 60fps (and that's with vsync on and a 60 Hz monitor so probably easily capable of higher). I am running Windows 7 x64. CPU is an i7 930 overclocked to 3.8GHz with 12GB Triple channel RAM and a GTX 460 (I'm not mad by the way, it's primarily an audio production rig in case you were wondering) and don't seem to have any dips even below 50fps looking down at Whiterun on 1680x1050 with most stuff turned to ultra. So there's definitely nothing rubbish on the hardware side and the game's most awe-inspiring sights don't seem to slow it at all. I'll be looking round a small interior and suddenly it takes half a minute to quicksave. Hitting escape seems to show the menus running at a normal speed though.

Hope this gets fixed having this issue as well. Sometimes I can play for hours other times only 20min then same thing happens i leave an area load up the next area and get slide show of 3 fps don’t matter indoors or if I am outdoors i have to restart the game to fix it.

It happens to me and I am unsure why. I can run the game on high, so it's not a mediocre graphics card (although it is getting time to upgrade) and so far every 5 minutes the game essentially runs super slow, to the point where I just alt tab and watch half a episode of Archer. Hopefully this will get remedied with the coming patch, as I would like to hold off replacing the 9800 GT until I really have to.

I just applied the tips from the ini thread and the uGridsToLoad thread. So, disabled in game AA and forced 4xAA VI the nvidia Inspector. Suddenly the drops as describe here occurred in indoor areas. I changed the AA mode to 2x in the nvidia inspector and the drops disappeared. Have the feeling it is connected to VRAM usage. I would like to hear from somebody encountering these indoor stuttering problems as well, if reducing or disabling AA helped with the issue.

I have this problem also, but usually only after some hours of playing. It seems to happen in areas that are much different from the surroundings. What I do is save, quit, and reload, then I get several more hours of lag free. Exiting to main menu and reloading does not work. I have not tried the ctrl-alt-del. Maybe a texture or graphics buffering thing, or a leak of some kind (since it only happens after some length of playing in my case) Hope the cause of this issue is found.

I think some of you are bringing up different issues. This is not about low fps in general. It is not about low fps in combat. The problem description is: you are running the game fine. With high fps. Then you "switch maps". You can switch maps by going indoor or going from indoor to outdoors. Or maybe fast-travelling. As soon as the loading screen disappears, the framerate is really low immediately. 5-8 fps in my case. While it is 25-60 fps normally. The low framerate does not go away by itself. I have to quit and restart the game. There might be other ways to force something that makes the framerate normal again, but for me most things didn't work. Only a restart of the game.

This is not a memory-leak, btw. I'm not going to explain in detail what a memory leak is here. But most non-programmers seem to have weird ideas about what a memory leak is. Memory leaks are bugs that cause a part of a program to sometimes not release memory when it should. Usually, over time, the program uses more and more memory. Programs will usually crash when all (virtual) memory is in use. That generally means 2 GB in use for a 32-bit executable. When using the large-address-space change, the limit increases to 4GB. This assumes that people have HDDs large enough for a 4GB pagefile.

The d3d9.dll + the 4gb patch fixed all my fps problems. At first my game was really Unplayable, the fps lag was horrible even at medium - low with no aa i had about 10 - 15 fps no matter where i went, i knew the problem wasn’t my pc since i play the witcher 2 with uber sampling with a playable fps. But when using the d3d9.dll + the 4 GB patch i play on ultra with fxaa enabled and my fps is smooth as butter and i experience no lag at all.
