Low fps, bad performance on gtx 970

[arvinzd]

I saw similar thread but it's a gtx 980.

And it was 6 months old thread.

 

EDIT:Wait a minute, did i post this in the wrong sub forum???

 

 

(I play on 1080p,ultra)

 

 

I clean install skyrim,then proceed

To mod them right away,before i played it.

 

I installed realvision enb,some heavy textures mod,paralax and graphics overhaul (like roads,lightning)

 

Exactly the same issue,when i see the mountains outside whiterun,

i get low fps,so i disable mod one by one,the weird things, i dont see any significant fps gain only 3-6 fps,i become suspicious ,so i turned off all the mod and,play vanilla skyrim.

(yes,i delete the skyrim.ini and skyrimpref.ini after Uninstalling all mods)

 

And

 

I get 32-28 fps. But in dungeon, when not looking on demanding view spot, it's 60 fps.(this is without mods at all)

 

I just couldn't make a sense about this.

I mean i can play shadow of mordor ultra easily, i even crosscheck,compare the fps benchmark on Internet, and i have the same,if not, higher fps.avg 75 fps

 

I can also play the witcher 2 enhanced edition, ultra easily,35-45 fps,with ubersampling on of course.

 

 

Can anyone help me??

My spec:

i5 3330

Gtx 970

Ram 8 gb

Psu 500w bronze corsair cx500

windows 8

Hi

 

I used a GTX 970 for a while at 1080 with ENB.

With an i7 2600K my average frame rate was in the mid 50s out side without DoF . That is with 250+ mods & 2k texture pack.

I repaced it with a GTX 980 sc that averaged in the low 60s.

 

Use the S.T.E.P. guide to help get better frame rate. http://wiki.step-project.com/Guide:ENBlocal_INI

 

To give you an idea of what a 970 can do without ENB. My average frame rate a 4k(3840 X 2160) was 74fps with the same mod setup.

 

Mods can give you a CPU frame rate hit through meshes & scripts. I am now running a GTX 980 ti sc at 1440 & all my frame rate drops are CPU. I get the same frame rate drop approaching Whiterun as I did with the 970 & 980. The exact same numbers for all 3 cards.

As this explains it...don't use 4k.

This is an old article, but...

"Simply put the GTX 970 is only able to fully utilize 3.5GB out of the 4GB of available VRAM optimally. While the card can still access all 4GB of VRAM, the last 0.5GB of memory is not accessed or managed as efficiently as the rest of the available memory. Which leads to the reported performance degradation when an application needs to access more than 3.5GB. In the examples Nvidia provided to the press the performance penalty is in the mid single digit percentages. However we don’t fully know yet if in other usage scenarios the memory issue will prove to be more detrimental. As there’s evidence that it has a more perceptual impact on frame time consistency rather than FPS which can be perceived as the stuttering or choppiness reported by Nvidia users on the GeForce forums."
