I also have this problem in our project, which is due to release in December this year. I cant seem to be able to fix this, all my sounds have 48k sample rate. I dont have this problem on my desktop, but some of our testers have this problem. Whenever they try to fire, the fps dropped dramatically to the point that it froze the whole game for 10-15s (their pc spec arent bad, can run PUBG just fine). Is it fixed in 4.24 tho ? Thank you
