Address Library for F4SE Plugins
Upscaler Base Plugin


  • Install all the dependencies using vortex or MO2, for Upscaler Base Plugin you just simply install it to data folder, I mean drag the whole UpscalerBasePlugin folder into Data, or install in MO2, the Data stucture should be like Data\UpscalerBasePlugin.
  • Extra step for UpscalerBasePlugin´╗┐, cuz I can't include dlls from Nvidia/AMD/Intel, you need to check its description and download the dll for the upscaler you want to use and put them in the UpscalerBasePlugin folder.
  • Press END in the game to open the menu for upscalers.

  • This plugin also forces ReShade to render after upscaling and before UI. 
  • DLSS/FSR2/XeSS don't work with ENB, but you can still use DLAA with ENB since there's no upscaling
  • Non-RTX card doesn't support DLSS/DLAA, but you can use FSR2 and XeSS with it.
  • But since both FSR2 and XeSS has no official DX11 implementation released, I was forced to make a DX11/DX12 hybrid solution, so your card must at least support DX12 to use FSR2 and XeSS
  • Added FSR2 Native DX11 Implementation! This should boost performance and fix many compatibility when using FSR2.Check the UpscalerBasePlugin´╗┐ page!
  • Upscaling is implemented based on the dynamic resolution scaling feature which is incomplete and hidden in the game, thus there might be issues related to DRS. I don't answer for issues related to DRS and I can't do anything to fix them.
  • This mod isn't compatible with FO4VR. I'll develop a dedicated FO4VR version as I did for SkyrimVR.´╗┐
  • Performance gain depends on how much you are GPU limited, if you don't see any gains it's very normal, you are most likely CPU limited.
  • Even if you can't get more FPS in a CPU limited case, you are however getting the superior AA from the DLSS pipeline, it's much better than TAA, or you can just use DLAA (with performance cost).


    Compatible with 1.10.163.

    DLSS/FSR2/XeSS not compatible with ENB.

    Not Compatible mods

    Crafting Highlight Fix maybe incompatible, some reported incompatible while some reported otherwise.

    Other mods not tested.


    After learning modding with SkyrimUpscaler, I've grown to make this mod on my own this time.
    Thanks to CommonLibF4 for making f4se plugin so easy and similar to skse plugin.

    Still all the appreciation for those who helped in SkyrimUpscaler.
