Loosing 100 FPS when i install ENB

[ENBSeries]

GPU Clock is working harder with UnsafeMemoryHacks then is is without

Ignore gpu usage statistics, it's totally lie and have nothing in common with cpu usage and how people understand it should work.

So, if ReduceSystemMemoryUsage=false do not affect frame rate that much and these last two tests are correct, then i can't help in anything absolutely. As i mentioned, if performance drops with unsafe memory hack it's not ENBoost/ENBSeries. Get the latest version and check what happens when fps is lower while unsafe memory hack disabled, it's in "profiler" of editor as number of textures created and how much memory per seconds for creating and deleting textures. Just make a savegame at the place where it definetly slower (120->30 fps f.e.) and do not turn camera and watch what is going on there. Also amount of available memory must be bigger than 64. Do not set autodetect vram size and amount of vram set to 12000. If these profiler statistics will not show all the time data transfer and creation of textures, then detected video memory size is correct and fails are totally on driver side, otherwise there is a some chance it's other software or OS (but driver is culprit #1 anyway).

If you're still having problems, try asking electricsheep how he got his Titan X setup working. You can find his posts in the Skyrim gallery often. Send him a PM maybe and have him look over here? It sounds like there are some very strange things going on and it might take someone who has experience using the same GPU to help you out. Hope you get it working!!

Just seen this, assuming these are your correct specs:

AMD Phenom II 965 x4 3.41GHz
EVGA Superclocked GTX Titan X
8Gb 2400mhz Ram

I haven't read this thread in full, but at a quick glance I would say your GPU is severely bottlenecked by you CPU, see this benchmark comparison:

http://www.cpubenchmark.net/cpu.php?cpu ... 965&id=370

Skyrim becomes very limited by your CPU performance when modded, other games too will limited by you CPU.

I would recommend at least an Intel i5 series processor, overclocked to 4.5ghz+, otherwise you won't be getting the full benefit of your Titan

Hello folks, my first post in this forum!

Electricsheep, would you mind sharing your enblocal [memory] settings with me? Since it was mentioned you got your Titan X setup working (I use a single Titan X + 5820k, my Skyrim needs currently 3,5-4GB of VRAM while running to give a brief idea of textures installed, I use mostly 1/2k textures, few 4k, but have alot of stuff covered overall). I am uncertain on how to minimize memory / loading related CTD chance to its minimum... since they occur every now and then.. I think mostly on cell transition, not sure though (I am certain its not scripts and i am also not hitting the 512mb limit set in SKSE memory patch)
I am not lazy, I have currently browsed this whole forum and half the internet for information about these settings, but I'm still uncertain... so I decided to sign up here and maybe get some input from the veteran modders or maybe even the master Boris himself!

My current settings:

[MEMORY]
ExpandSystemMemoryX64=true
ReduceSystemMemoryUsage=true
DisableDriverMemoryManager=false
DisablePreloadToVRAM=false
EnableUnsafeMemoryHacks=false
ReservedMemorySizeMb=512
VideoMemorySizeMb=10240
EnableCompression=true
AutodetectVideoMemorySize=false

I have a couple of questions:

1. ReservedMemorySizeMb... I am particulary uncertain about that.. I mostly read values of 256 or 512.... From what I have read it is the amount of memory that gets not allocated by ENBoost and at the same time gets a dublicate in RAM... so more but slower memory for Skyrim... So why not set it to zero? Other programs running in background (windows, crapware, antivirus) have enough VRAM left and ENBoost could work with VRAM only, wouldnt that be a benefit?
Does more RAM usage mean more CTD chance in general (because RAM too slow)?

2. STEP forum claims ExpandSystemMemoryX64 must be set to false if using Unsafememoryhacks.. is this credible information? And Do I need Unsafememoryhacks in my setup? I read its necessary if VRAM high compared to texture size ingame

3. A while ago there were wild discussions about ENBoost interfering with SKSE memory patch... Is this still something to consider and a source of CTD? Since I guess almost everyone uses both SKSE memory patch and ENBoost...

I am very grateful for any help!

Regards,
Umaril

EDIT: I tried DisableDriverMemoryManager=true and Unsafe memoryhacks, still random CTD while running around exterior, maybe even more. What I noticed in this mode while running outside fast black meshes without textures can occur, does that mean textures can't get loaded in time? Do i have too many textures for my system?

[MEMORY]
ExpandSystemMemoryX64=true
ReduceSystemMemoryUsage=true
DisableDriverMemoryManager=true
DisablePreloadToVRAM=false
EnableUnsafeMemoryHacks=false
ReservedMemorySizeMb=1024
VideoMemorySizeMb=12288
EnableCompression=true
AutodetectVideoMemorySize=true

ReservedMemorySizeMb - 1024 is a bit high but gives me less lag with my setup, normally 512 is max recommended

ExpandSystemMemoryX64 - I have this set to true without problems, not sure about that advise but setting EnableUnsafeMemoryHacks to true will give you better performance (less lag) as long as you don't exceed your VRAM

I use ENBoost with SKSE memory patch without any problems

The black meshes mean textures have failed to load, try my settings with he latest binary with the new version of enbhost, ensure no unnecessary background processes running and use vanilla game ini files (except for edits needed by ENB)

[ENBSeries]

Black or blue textures only may appear when EnableUnsafeMemoryHacks=true set. Otherwise mod keep uploading textures at any cost. This is bug somewhere else, with other mods, crapware, may be wrong texture set, invalid skyrimprefs.ini/skyrim.ini tweaks regarding multithreading.

[Umaril]

Thanks alot for your responses! I always keep my distance from questionable ini tweaks circulating since 2011

I might just go ahead and compress my textures a bit and try Electricsheeps local.ini.. One does easy go overboard with textures when everything has to be ultra HD.

@Electricsheep The ini is similar to what i found to be most stable.. But you disabled Videomemorydriver, thats interesting... Is the Driver performing poorly for Titan X? What does it do wrong?
And do you get slight stutter / FPS drops at cell transitions (I assume you use at least ugrids7?) or non at all? You never get random CTD's due to memory issues?

[electricsheep26354]

Umaril
My current setup is very stable, no CTDs with ugrids 11, 8k resolution and 60GB of textures - I get some stutter but my game is very overloaded - optimised only for quality screenshots. The driver setting doesn't make much difference, performance is slightly better with it disabled.

[Umaril]

Thanks for your input... Your settings quite stable for me at first tests... cell transition lag only when running fast with speedmult 200+ ... But I guess thats completly normal, nothing can stream that massive amounts of textures that fast ..... AutodetectMemory says about 4GB of texture memory detected? Why doesnt it detect more? Is it because it's the max amount of memory for ENBhost.exe before a second ENBhost.exe spawns, and only if the second one spawns it will detect 4 more GB of VRAM during ingame?

And just out of curiosity, if its bad to explain to noob user ignore : What I still dont understand why does one need ReservedMemorysizeMB when you have tons of VRAM... guess I still don't understand that setting after reading so much about it .. from what I know it is VRAM that gets mirrored in RAM and does not get allocated by ENB mod... but isn't it good when ENB mod use VRAM not RAM, because VRAM is faster?

[ENBSeries]

Autodetected size is the real limit for you driver and hardware, any dx9 games can't use any bigger value and ENBoost also utilize only that amount of memory, everything else not fit to that amount are sent to enbhost.exe processes. The real problem is why the heck many users with huge amount of video memory have only 4 gb (VRamSizeTest tool also report this), why the same videocards for others show a lot of memory available? Something in drivers is wrong or affect drivers and i have no idea how to find out (nvidia forums seems do not have any professional support, just crowd of fanboys).

Reserved memory parameter is safety area for ENBoost itself, for graphics of ENBSeries, for other processes which use video memory (almost all modern i-net browsers, skype) and conditions when too many mods installed with not enough video memory available, like your case (4gb, mine autodetected is also 4 ).
