Improving Preformence

[AssAssin40k]

I have a 3g EVGS Geforce GTX 780 graphics card with an Intel 7core processor running on windows 7 64 bit OS and still experience slowdowns and lag spikes sometimes while playing. How can I mitigate these?

Did you read skyrim stability guide?

[PetPet]

Have you tried using "Skyrim Performance Monitor" to track what is your system bottleneck during those lag spikes moments? I am assuming you already have SSME (or SKSE equiv) and ENBBoost enabled...correct?

 

(Again, I am assuming you have ENB installed) If you are willing to take risk, or just want to rule out memory usage being a factor, you can go to enblocal.ini and flag "enableUnsafeMemoryHacks" to "true". This will force the system to max out VRAM usage (which usually is your system's fastest RAM). FWIW, I set this feature to "true" for months and it pretty much eliminate all staggering for my GTX 780 6gb non-SSD environment. S.T.E.P. explains this setting as below:

 

"Enabling this parameter is generally not safe. This is a workaround for users experiencing large amount of stuttering, typically on systems with large amount of VRAM (4GB+). When enabled, it does not use memory reallocation, compression, or enbhost.exe and will only work when ReduceSystemMemoryUsage is also enabled. A known bug is that Alt+tab will not work in fullscreen when this is enabled."

 

Good luck.

Could you tell me more about this? What are the risks?

[PetPet]

It is marked as "unsafe" by the ENB author, hence the risk. Though as I mentioned, I have been using this option for months and I am essentially getting SSD performance with a HDD setup.

 

Another thing to consider, your card has 3GB onboard (mine has 6GB, though my CPU clock speed is lower than yours), which may or may not have enough VRAM to cache every hi-res textures you put Skyrim engine to load. Also, "enableUnsafeMemoryHacks to true" essentially disable enbhost memory partitioning, thus you are at the mercy of hitting the 3.1GB (or worse in some cases) process memory ceiling. TL;DR version...I essentially give up loading too many hi-res content, while gaining a stagger-free environment in return. One more note, I did use "Texture Optimizer" mod quite a bit.

 

Seriously though, try "Skyrim Performance monitor" first, as it tracks memory AND CPU usage (as well as others).

 

Hope it helps.
