I get low FPS when using scopes. It seems to be less when using a PSO (any which one) compared to the hunting scope. It seems it's tied to how far 'said' scope can zoom in. The issue occurs specifically when aiming towards trees (real bad when aiming at the actual crown of the tree). The FPS loss when aiming at a pinetree is lower, but the birch tree specifically is real bad. The FPS loss when going from not using the scope to fully zoomed in using the scope is from 70-100 FPS to 15-25 FPS, the further i zoom in with the scope the lower the FPS gets. It occurs in a lot of places with lots of foliage doesn't have to be specifically birch trees but they are the worst. I have tried changing pretty much all my settings from 'high' to 'off/low' and it did change my FPS when not using the scope, but when I zoomed into the birch tree it always had pretty much same FPS (gained about 2 FPS when turning AA off) The only setting I could change where it would have a significant change was the game resolution. I play at 2560x1440 because that's the native resolution of my monitor, when I change resolution to 1920x1080 and aim into the same trees as I did with 2560x1440 resolution I have about 35-45 FPS as suppossed to the 15-25 I had when on the 2560x1440 resolution. To begin with I thought it was my computer not being powerful enough, but I just find it strange how I can have 70-100 FPS and then go to 15-25 just because I use a scope. I played at 2560x1440 in older patches too and didn't have such big issues when using scopes as I do in the current stable patch '0.60.133617' I've specified the severity as major, because the game is near unplayable when using a scoped weapon (tested with Blaze with a hunting scope) I haven't found some binos to test it out with but I'm almost certain it would have the same effect because I believe it has something to do with the zoom level and LODs
