I bought Skyrim recently. As the title suggests, my performance drops after entering and leaving houses a couple of times.

My build is Intel i5 quad core processor, NVIDIA GTX 560 Ti from Gigabyte (stock-OC, manually downclocked to fix the CTD issues I had before with Skyrim and BF3), 4GB RAM

A game tweaks website suggested that my slow hard drives might be a problem. A screenshot of a Windows Performance Index sample with the subtitle "This is likely to cause issues" showed the HDD with a performance index of 5.9, the exact same mine has, so I am considering purchasing an SSD.

I've tried different solutions: ENB Series, removing certain mods, checking my FPS Rate, monitoring my resources, .ini tweaks. It's all just fine, I don't see what I'm missing. Any thoughts?

@Renan Thank you for the advice, I'll post my question there as well. –  Derija Mar 31 '12 at 21:26

A lot of this background is more appropriate for a blog than a Q&A site. I've removed the fluff to make the question more succinct. –  BlueRaja - Danny Pflughoeft Apr 2 '12 at 19:52
Sorry, I have a tendency to write a lot. ;) –  Derija Apr 4 '12 at 2:04

Have you been using many mods? Some are known to leave garbage data in saves that slows the game down after the mod has been updated or removed. Try starting a new game with 0 mods and see if the slowdowns continue.

Also, make sure your mods are compatible with the version you're running.

Looks like my comment has been ignored. Here we go again: Although I didn't believe that this is the issue, I still tried it and got proven right. The problem still occurrs. Thank you for your quick suggestion though. I hope it's not a hardware issue, but I think it unfortunately is. –  Derija Mar 31 '12 at 21:34
I'm not sure what comment are you are referring to. You've only mentioned removing "certain" mods, not trying a new clean game. –  kotekzot Apr 1 '12 at 3:10
I was referring to my own comment, it didn't get submitted. Maybe I accidentally pushed the wrong button, just don't worry about it. However, I did try a new clean game after reading your answer. –  Derija Apr 1 '12 at 3:22
Oh, derp, sorry. Can you tell us more about your HDD? –  kotekzot Apr 1 '12 at 3:47
Well, it's as old as my PC, I didn't replace it yet, so it's approximately 2 1/2 years old. 1TB storage and I'm not even sure anymore whether it uses SATA or IDE, but I believe the first is the case... I'm not that good at hardware. Here's Window's performance index. My system is German, shouldn't keep you from understanding it though. I've used a tool to get these results. What else information do you need? –  Derija Apr 1 '12 at 4:54
