Does the pro have this issue?

Any one else playing on standard ps4 (not the pro)… Getting some rare but extreme jerky frame rate slowdown during activity intense moments?
Only happens in a few places…one is in the wildlife preserve, outside the building of bloodwings enclosure after killing loaders and stalkers the door opens and a boss loader fires at you…it doesn’t freeze the game but it looks like it’s about too…it’s not often enough to spoil the game but this has me worried about Kreig working in vr as he looks to have a lot of visual effects happening with his special skill.
Anyway I’m wondering if having a Ps pro would eliminate this issue.
Tap like if you have this happening too…I’m hoping it’s not something wrong with my ps4.
