FPS Drops when running any ENB


calbin

Recommended Posts

Without any ENB, my laptop runs fine on ultra even when I have about 10gig or mods loaded.

My computer:

i7-3630QM

Nvidia Geforce GTX 680M

16gb DDR3 ram - Windows 8 64bit

Running Geforce 314.22 drivers

 

My suspect is that for some reason, ENBs causes my laptop to run Skyrim using my Intel® HD Graphics 4000 instead of my GTX 680M.
When I first run the SkyrimLauncher after installing an ENB, it sets my default graphics to Low. I go into options to check which card is running and without a doubt, it is the Intel® HD Graphics 4000 rather than GTX 680M. Furthermore, I do not have the option to choose my GTX 680M.

 

*edit*

I noticed that in my SkyrimPrefs, I see

sD3DDevice="Intel(R) HD Graphics 4000"

So I changed it to Geforce GTX 680M. Then I ran the skyrimlauncher again, but to no surprise, it chooses the HD Graphics 4000. I go back into skyrimprefs and see that sD3DDevice changed back to HD Graphics 4000.

Question -

 

Do you have 20 FPS or 45 FPS with ENB?

& ENB does not do anything to the driver selection in Skyrim... it's because mobile gfx cards are not very supported... I think the game still uses your gtx680m

 

and don't forget, ENB is software rendering, not hardware, so yes, FPS drop, as much as 50% in some cases.

Just use the injector version of ENB instead of the Wrapper, since you likely have Optimus enabled.

Hi guys, I´m also having the same problem I think.

I actually have Seasons of Skyrim ENB installed. However Im using a desktop PC not a laptop. I have an ASUS GTX 760 without any HD textures mod installed,

however with the ENB enabled I´m getting 15 - 30 FPS outside, but, and this is the misterious thing, the games runs at 50 - 60 FPS inside interiors & dungeons.

 

I also tried RealLike ENB which is suppossed to run smoothly, but I get the same FPS rates.

I´m using Enhanced Lights & FX mod for lighting, SSAO, SSIL and Depth of Field are disabled on ENB.

 

I´m getting mad with this problem because IMHO my GPU should run the game at higher FPS. It runs at 60 FPS in ultra without any ENB, so I hope together we can find a solution for this.
