I recently bought XFX Radeon Rx 5700 XT. After installing the device on my pc, fps suddenly drops on overcrowded areas in MMOs. Sometimes it's impossible to multi-task (alt tab-ing) because it often blue screens when I did. I play Final Fantasy XIV and their system requirements is very low. I also tried Tera and it also showed the same fps count
In non MMO games such as CS GO and Monster Hunter World, FPS was normal.
Summary of what I did so far:
Here are my other specs: Intel core i7-6700K Processor
