Sudden and constant fps drop (from 50 to 15), often after entering new

Np Feanoro, happy to help :thumbsup:

hello again!

 

i did a lot of things again: bought another 4GB of Ram, testet the gamebooster (fixed nothing, not even better fps) and tried several driver versions (incl the latest non beta driver, 285.62)... and it helped.. nothing.

 

the only thing helping is pressing ctl+alt+del and "cancel" (not even entering the tast manager in vista), afterwards fps are fine. this makes the game working almost fine but isn't really a fix.

 

from this my conclusion as the vram buffer is most of the times full (>1000mb of 1024mb) is that it's a vram issue, i'm not sure if it's a driver issue or a skyrim madly coded or 1024mb vram just aren't enough for maxdetails, 1080pix and some texture mods. if anyone has some more ideas, please let me know.

CPU is binding. You can try running skyrim in windowed mode (i use Simple Borderless Window) and try SkyBoost (found on google and on the nexus).

I'tt have a try, is it better than TESVAL?

 

but my cpu (Intel core i5 2500k) is definitly not binding, it's rather bored, having not more than approx. 50% load at any time or in any core.

Hi there. I've been having the exact same issue and it's very annoying. I was wondering if you found a solution?

 

My system: i7-950 OC'd to 4ghz, 12GB Ram 1333mhz but running at 1500 due to OC. Asus GTX 570 DC2. Running at stock values. Win7 64 Bit. CPU is water-cooled. GPU has its own fine cooler. No temp problems.

Right now using driver 296.10 which is the latest.

 

So far the only thing that works is ALT+TAB, nothing else.It's really annoying.

My Skyrim is heavily modded. ENB is on and using Bethesda's High Res. Texture pack. Running on 1920x1080 res. and ultra settings.

I've finished the scenario more than 10 times and i'm pretty sure i was playing the game very smooth between 50-60fps. It was like a month or 2 ago. I can't remember when exactly this issue started showing.

Tried downgrading drivers, changing gpu values and things mostly mentioned. Only alt+tab rescues me for some minutes..But after a while it starts happening a lot more frequently. :wallbash:

 

If this is something related to coding of Skyrim then why not everybody having this issue and why not Bethesda doing something about that? :wacko:

i'm curious about what you said, because: I do already have an SSD (though skyrim is not installed on it), I habe 4GB of Ram (which should be onough, i guess..?!)

 

No, if you have 4GB, 2GB of that is being used by your Operating System. If you have Vista, 3GB are being eaten by your OS before you even start playing the game. That leaves only 1 or 2GB for Skyrim. The same thing happens to me, and I have 4GB of RAM. I'm getting 8GB as soon as possible, and hopefully that'll fix it.

 

Edit: Huh, you said you already bought another 4GB? Well, with 8GB total then I'm not sure how to fix this.

@born2bemad: Do you use the latest patch for skyrim? how much VRAM does your card have?

 

I came to the conclusion its a vram memory adressing issue, what finally helped me, was:

 

reducing the shadow details to medium. shadows do even look better in my eyes and afterwards this bug did not occur anymore. (may be a patch issu, too, because while i changed shadow details I patched skyrim)

[Rennn]

Yeah, Skyrim has a comparatively large memory leak. To cut down on tha you could go into your Skyrimprefs.ini and set [Particles]

iMaxDesired=250. It's not much of a quality decrease, if any, and although I haven't tested it much it's supposed to help this issue.

Yes i'm using the latest patch for Skyrim since it's bound to Steam, the game patches itself automatic. I'll try reducing shadow details now, i hope it helps me too.

Btw my card has 1280MB VRAM.

Seems many are experimenting a bad case of memory leak. I mean chunks of memory allocated and never released before allocating more. That would explain why passing the control to the OS, like going to desktop and returning alleviate the problem, Windows will identify the orphaned blocks and release them.

 

Although not directly responsible for the problem, the high resolution texture packs help reducing the available memory and making the issue manifesting to the user sooner.

 

I have not been playing long times recently to tell if it happens to me too, but would be useful having the load order of those suffering the problem, maybe something in common in there may help the troubleshoot.

 

A dirty workaround until the real causes are found may be using a memory monitor utility able to periodically clean it from those loose chunks (working in the background, like gamebooster does. Maybe gamebooster itself has that feature, I don't remember), at least delaying the problem.

 

Make sure to save the game at reasonable frequency.
