Need help with skyrim performance / lag spikes


Alan47

Recommended Posts

Hello everyone,

 

I'm struggling with the performance of my modded Skyrim. Sometimes it runs smooth as silk at 60 FPS, sometimes it drops to 10. I failed to pin-point exactly when and where the FPS drops happen, so I ran Skyrim Performance Monitor:

I took this sample while doing the Bleak Falls Barrow dungeon. If you look at the GPU usage graph (orange), it goes up and down like *crazy*. Is this normal for Skyrim? You can also see the FPS spikes I am talking about (blue). The available VRAM is obviously not the problem (was my first guess).

 

Here are the most important hardware specs of my machine:

CPU: Intel i5 2500K, 3.30GHz

RAM: 8GB

GPU: AMD Radeon R9 290, 4GB VRAM, latest drivers

Disk: Samsung SSD (Skyrim and MO are installed on the SSD)

 

Here are the screenshots of the other two tabs of the performance monitor (those that deal with INIs):

Is anybody else experiencing these strange lag spikes? Any help / hints / useful info? I really love the way my Skyrim looks and feels with RealVision, I wouldn't want to play it without ENB :(

 

 

I'd be grateful for any advice.

 

 

Thanks,

I think I've figured it out. It's a really odd story. Read on if you're interested.

 

So I had these lag spikes in my game. By temporarily disabling ENB completely, I got *no* performance gain at all. None. Zero. That, plus the fact that my graphics card seems to be idle rather often (when really it should be working to produce more FPS), lead me to the conclusion that apparently the game was doing something on the CPU that was dragging down the frame rate. So I looked for INI tweaks that improve Papyrus performance, tried that, and the situation did indeed improve, however only by ~5 fps.

 

Then I went over my mod list and checked which mods were script heavy. Or rather: which I *assumed* to be script heavy. On a mod list like mine, that took a while. Eventually, I came across HDT Physics Extension. "That might be a candidate" I thought and investigated. I opened up the Physics Extension log file.

 

The log file was FILLED with error messages.

 

The error told of an animation which was trying to access a skeleton bone, but that bone was not there. And that message repeated. OFTEN. So the problem was clear: the Papyrus engine was so damn busy to write dozens of these messages to the log file each frame (!!!) that the game started to lag heavily. Okay, so the source was clear. However, my player character uses the latest XPMS skeleton there is - no chance that this would cause such a message.

 

That was when I noticed: with no follower around, my game was running smoothly. Also, no messages in the error log. Lo and behold, the source of all the trouble: I'm using Emily, a custom follower. And guess what: she comes with her own skeleton which caused HDT to freak out which caused my game to lag. Replaced her skeleton with the current XPMS, and my FPS went from 17 to 47.

 

 

Damn. That was a hard nut to crack - but it's working fine now.
