After struggling with low FPS in Apex Legends, spending a lot of time researching for ideas to improve my game experience I've found one time a really interesting post when searching for an issue I was having with another application (GamingOSD). I've found that uninstalling ALL versions of Microsoft Visual C++ YEAR(s) Redistributable .... (I had installed like 6 different versions) restarting and reinstalling the latest one (just google for Microsoft Visual C++ Redistributable) my FPS increased so much that I now can play, I have gained a boost of at least 30%.
Hope this helps. It helped me a lot.
