SPT 3.8.3 Compatible
Dynamically change the resolution of the external image rendering when we enter the optical sight, which gives us an increase in frame rate
How the idea originated:
We all know that Tarkov uses a “Picture in Picture” system for optic scopes
And previously (before patch 0.13.05), the resolution of the internal rendering picture (in optic scope) depended on the resolution of the external rendering (player camera). So, if we lowered for example FSR 2.2 to level “Ultra Performance”, it gave us good gain in fps from player’s camera (external rendering), but very badly worsened image when we look through the optical sight (internal rendering)
Now (after the 0.13.05 patch), the external rendering resolution (player camera) has no effect on the internal rendering (in optic scope), I say even more, now the image in optic scope is always rendered in full native resolution
And that’s why I came up with an idea to dynamically control the resolution of the external rendering directly (player’s camera), and without any loss in the quality of the internal rendering (in optic scope)
This mod works this way:
1) It checks what scaling method is used (or lack of it) and with what settings
2) Then when you look through the optical scope, it lowers the resolution of the external rendering (a picture of what is outside the optic scope) to the specified in the BepInEx config
3) And when you exit the scope, it returns your previous settings
In the end this gives a very nice performance boost, BUT if you don’t have a “bottleneck” on CPU performance
Known issue (idk how to fix it so far, it’s beyond my capabilities 
- Not compatible with SurroundDOF option in Amand’s Graphics
- Not compatible with Motion Blur option in Amand’s Graphics - When using FSR2/DLSS and entering in optical sight, the screen will blink - Not compatible with FXAA anti-aliasing
Installation:
1) Download file
2) Place this file in BepInEx/plugins
3) The mod works automatically with the default settings of 50% downsampling if FSR 1.0 or FSR 2.2 are not enabled, and 50% downsampling if FSR 1.0 or FSR 2.2 are enabled

Thanks to MarsyApp, who listened to me and tried to implement it, created a “base”, which later I refined a little bit
Thanks to DrakiaXYZ for overall mod improvement

First of all, I want to express my gratitude to DrakiaXYZ 
Changes:
- Add compatible with DLSS method
- Now mod agnostic of the SPT version (i.e. compatible with future versions SPT, much appreciated to DrakiaXYZ)
- Improved Switch Sampling - for now only for usually SuperSampling (not FSR1|2 or DLSS), this change remove black screen when entering into optic scope
Known Issue:
- Not compatible with SurroundDOF option in Amand’s Graphics (idk how to fix it so far, it’s beyond my capabilities )
Tested on 3.8.0 and works fine

im in love this mod pleaseee update it to 3.11
Found a fork that actually works in 3.9.x. its a personal build so it might be a little different, but it works nonetheless: https://github.com/DrakiaXYZ/SPT-Dynamic-External-Resolution/releases/tag/4.0.0
adjust for 3.9.x github
work absolutely fine for me at 3.8.x i can now use scopes with basically insignificant fps drops , I hope it will get updated to 3.9.x
Great MOD
i need this on 3.9.2 :c i cant play without this mod, Vanilla tarkov scopes are shit and drop mi fps from 50 to 10
Жаль, но мод приводит к бесконечной загрузке 3.9.2(
This mod is amazing. Nothing else to mention about the functionality, on my side at least.
A suggestion: BSGs native implementation of super sampling is SH*T. 200% murders frames more than putting the actual resolution at 200%. I suppose this has something to do with how they calculate it and it not being correct… What could be added is a proper modern-style custom resolution scale for the normal resolution as well (for us that have the extra headroom)
“The mod works automatically with the default settings of 50% downsampling if FSR 1.0 or FSR 2.2 are not enabled, and 50% downsampling if FSR 1.0 or FSR 2.2 are **enabled”**
was that a typo, because it makes very little sense to say it like that. Other %es maybe?
It’s amazing.but i found it’s unstable in3.8.3at least.in shelter,fps is higher when adsing than not.that’s horrible! but in tarkov street fps is almost no changed. I found that in some maps,when in scope,graphic usage will drop almost 20%.if the mod is disabled,the usage won’t drop but it’s double render.as a result,fps not change.hope that the author could fix usage problem,waiting for update!
