Low FPS, Low VRAM-usage

[Minutemen2]

Hey Community,

 

I reinstalled my Skyrim completely because I started using DDSopt.

I DDSopted my Skyrim and HDDLC textures and my game run just fine with continuous 60+ FPS.

Afterwards I installed the HDDLC Optimized Mod and changed my Game-Settings to: no AA, no AF, high shadows, rest ultra

 

But then I installed an ENB (RealVision Performance, no DOF, no SSAO) and my FPS dropped down to 48 FPS outdoors without any INI-tweaks (except those necessary for ENB) or Texture-Mods.

 

Is this normal? My VRASM-usage was at 1.25 GB; my RAM-usage at 1.05 GB.

 

What can reduce the ingame FPS generally? Are there other factors that affect FPS except VRAM/RAM-usage?

 

My Specs:

Win7 Home 64Bit

16GB RAM

NVIDIA GTX 560 Ti 2GB VRAM

NVIDIA Inspector without any changes in TESV profile

Intel i7 2600K 4x3.4GHz

ASUS Monitor 1920x1080

ENB is software rendering

Yes it's normal. ENB may use up to 60% of your performance. Some performance ENB "only" use like 15% performance but don't look half as good.

 

I run a heavy modded game on an overclocked GTX680/4GB and hardly keep 45 FPS outside.

But my game runs at 90 FPS (tested with disabled VSync) without an ENB and with the performance ENB I hardly get 50 FPS outdoors. And I don't have any mod installed except HDDLC Optimized which increases performance.

HDDLC, optimized or not, does not increase performance from the vanilla.

And yes, it's normal.

 

I used to have a GTX560Ti and I got ~25FPS outside with ENB, now 45FPS with a GTX680.

 

ENB costs a lot of performance... If it's too much to your liking you can try something like this instead: http://skyrim.nexusmods.com/mods/37846/
