60fps with 4k and ENB possible?

[Bangbang!]

Hi guys,

I am by far not really good at modding and tweaking but slowly i am getting a bit further and further. Most recently I finally discovered the reason of my biggest FPS drops, my resolution was set at 4K.

My monitor is UHD, I've got a 1080 GTX TI but still whenever I enable my ENB (pretty much most that i've tried) my fps drop to 40ish outside). So i'm wondering, is it actually possible to run the game at a steady 60 fps on 4k with an enb enabled?

At 4k? Unlikely.

I'm running a decent system, though not superior by any strech (i7-7700 @ 3.6Ghz, GTX 1080 & 16GB RAM) and with ENB+ReShade at 4k resolution having no mods I run around with ~30 FPS. My monitor is at 1080p so I can utilize 4k res via GeForce Experience rendering the game at 4k and then downscaling that to my native res.
When I drop the resolution to 1080p, FPS stays rock solid at 60. I can drop some ~55GB worth of active mods on top of that still using ENB+ReShade and still stay at 55+ range.

4k resolution is pretty demanding. You're running some ~8mil pixels compared to ~2mil at 1080p (2k really, technically speaking). Four times more junk on the screen so no wonder even high end systems start to slow down.
Also, afaik Skyrim utilizes CPU a great deal for shadows for some mystical reason only Bethesda knows so that might be a bottleneck with top tier graphical settings, not so much your GPU.

If you're technically adept, you could try some tweaks to utilize more than two cores and/or SLI/Crossfire. Although what little I know, Skyrim doesn't handle these very well.

Thanks, this explains a lot! Il also try the downscaling option. Im no technical adept by any means so ill just stick with what i have. :)

I don't think downscaling will do you much good.

If you render the game at 4k and downscale it, it'll still eat up the resources without increasing the quality too much. You'd be better off just selecting a lower resolution. Try 2560 x 1440 or something if you want to keep 16:9 aspect ratio.

Alternatively you could utilize some cool widescreen setup. There are mods to support this, if you'd like 3440x1440 or some such.

Edit: Oh yeah, if you meant downscaling like just dropping the native resolution, then yeah that's the ticket. I was still thinking about my own piece of junk of a monitor while writing that.

Also if you trying to load those 4k files, that alot of data need to be transfer. What kinda of drive you have there? There a 3GB/s and 6GB/s, the 6 is SSD would be a big difference even if you have really good video card.

Jepp i am running everything on SSD. Switching back to HD makes such a huge difference in fps already, but having played on 4k even with the lower fps it is giving me mixed feelings.

I run 2k at 60fps with ENB but for 4k youre better off going into the Nvidia inspector and changing your vsync to forced off and your limit to 60 fps
