I have tested this on multiple machines and PS5 console and whenever you are using a scope (thermal or any) the game drops the fps by 10-20fps, The reason why it happens its because the game tries to render it by a 2nd time but at a lower resolution and LOD through the scope. Currently by now there's no fix for this issue you might as well wait for Mercenaries dlc patch for this problem to be fixed

Yes very annoying issue.
"Currently by now there's no fix for this issue you might as well wait for Mercenaries dlc patch for this problem to be fixed" Any official word on whether they will optimize this behavior? So, you mean the original view of the game is then rendered in the background in additions the view that is rendered through the scope? If true, that would cause this performance drop, but weird, normally looking through a scope narrows the field for rendering, thus improving performance haha
The scope simply renders the game in there but lower resolution and lower LOD, there's no fix for this
But the scope thus renders the game at lower resolution and LOD??? That is strange? But how is that causing the FPS drop? Or are the FPS drop and scope issues separate? Sorry, your way of describing issues is very confusing.... haha
Okay so, in most games, scopes on weapons use a hacky approach by simply "zooming" the current player view to emulate the effect. In this game, it's displaying a second separate view (layered on top) of the game that's zoomed in, inside the scope, effectively rendering twice. If the rendered view of the scope was crystal clear at the same resolution as what you normally see unscoped, you could say that would straight up chop your FPS by exactly half. The issue being, this game has done a poor job of executing this. It's far from being the only game doing this to achieve a realistic scoped view, but none of the said other games that I know of suffers from this kind of horrendous performance impact.
Capcom is very well known to be extremely closed towards their community when it comes to bugs like this, i expect this issue to be fixed in the mercenaries dlc alongside with the chapter 12 bug as well
Well, they publicly mentioned that the chapter 12 progress blocker will get fixed in an upcoming update: https://twitter.com/RE_Games/status/1641753718516318208 So, they seem to be open about some issues. But lets not make assumptions about whether or not developers will fix other issues as well, especially when adding that to PCGW: is still just speculation and when it is presented as fact on PCGW page, it can set false expectations for users.... Hence why I removed that bit and sources are good to use to back these claims up :)
https://steamcommunity.com/app/2050650/discussions/0/3823034248724657537/ Here it is also mentioned, people confirming this likely happens by the scope rendering a second viewport for the scope. Seems like this is done for a more realistic effect, so that it is intentional and most likely a non-issue. So, removing it for now honestly as others here also kinda confirm it.
