Realvision ENB , GTX 970 and.....Stuttering :(

[phoenixfabricio]

Hi everybody.

 

Stuttering is the most annoying issue in modded Skyrim and I'm trying everything to eliminate it or at least reduce at maximum. This is my current specs:

 

MOBO: Asus Z97-k
PSU: Corsair CX600
CPU: i5 4690 3,5 ghz (Turbo boost 3,9 ghz)
Vídeo: NVIDIA GTX 970 (EVGA)

Samsung HDD 1,5 Tb
8 gb RAM (Kingston 1600mhz)
OS: Windows 8.1 pro

 

I did a fresh install of Skyrim, and after, I install only the required mods (CoT and RLO and the patches) and Realvision (option A full with DoF and AO disabled, using DYNAVISION static DoF and NVIDIA ambient occlusion). No stuttering until so. But after I install about a half of recomended mods, sometimes stutter occurs!!! And this is strange because I reduced a lot the number of mods comparing to my another gameplay when I had a GTX 750 with 2 GB of VRAM (using performance version of RV) and incredible I'm having more stuttering than when I had the previous specs.... :sad:

My [MEMORY] lines of enblocal is now set to:

 

[MEMORY]
ExpandSystemMemoryX64=true
ReduceSystemMemoryUsage=true
DisableDriverMemoryManager=false
DisablePreloadToVRAM=false
EnableUnsafeMemoryHacks=true
ReservedMemorySizeMb=1024
VideoMemorySizeMb=9728
EnableCompression=false
AutodetectVideoMemorySize=false

 

I've been tryied various combinations without sucess until now. I also tryied diferent settings in Skyrim Launcher, skyrim.ini and skyrimprefs.ini, but stuttering persists. Mainly during cell changes when my character is running in world space....... In the next week I probably will have have 16 gb RAM (dual channel 2x8 gb) and I hope it can allow a good combination to override this problem. Maybe someone here have the same GPU and could give me a help. Thanks in advance.

EnableUnsafeMemoryHacks=true IIRC, this setting is mostly for AMD users.

 

STEP guide has the most detailed descriptions of settings for ENB inis that I've found, so check out this link http://wiki.step-project.com/Guide:ENBlocal_INI

 

There is quite a bit of discussion about Nvidia capping VRAM at "4gb" for 32 bit apps, while in reality it seems the cap is really 3.5GB. So, there's more than a single reason for stutter to troubleshoot. More details can be found at ENBdev.com forums. (This seems to be relevant to cards having 4+GB of VRAM)

 

If the stutter is mainly due to cell transitioning, possibly your HDD is not a performance drive? Or needs defragmented? Using EnableCompression=true might help...your hardware isn't too shabby.

 

Nvidia SSAO is more performance friendly, IMO, than ENB SSAO; however ENB does let you tweak it up a but.

 

Set AutodetectVideoMemorySize=false to "true" to get an idea of how much RAM should be assigned to VideoMemorySizeMb.

 

FOV can also make stutter, mostly when turning side to side, though. Forcing AA thru nvidia profile can also put a big load on rendering.

 

Good luck. :smile:

I'm thinking about buy a SSD. But I have seen people with stuttering issues even with Skyrim installed in SSD. And more, When I was playing with GTX 750 2gb I had much more texture mods than now and the stutter was rare, using the same HDD. I imagine that is some vallues of video memory and reserved memory that is the correct for my system. I didn't try 128, 384, 640, 768 and 896 in reserved memory yet......

[MEMORY]

EnableUnsafeMemoryHacks=true TRY "FALSE"

ReservedMemorySizeMb=1024 TOO BIG! I WOULD SET IT MAXIMAL TO "768" BUT TRY ALSO "512"

VideoMemorySizeMb=9728 WHY THIS VALUE?! TRY "10240" OR SINCE THE 4GB OF THE 970 ARE IN FACT ONLY 3GB "9216"

EnableCompression=false TRY "TRUE"

 

 

In the next week I probably will have have 16 gb RAM (dual channel 2x8 gb) and I hope it can allow a good combination to override this problem.

 

MORE RAM WON'T HELP YOU WITH THIS:
