I run a PNY GTX 1050 Ti 4G version, with 8GB ram, and an intel i5-4460 @ 3.2GHz. When I run Battlefield 1, the game plays beautifully for a while, then the sound begins crackling horribly, and then the game slows down, to the point of even freezing while the sound stops entirely only to suddenly recover. This always happens after the first 2 games or so, even with CPU priority at Realtime and all settings to power in Control Panel. However the game continues to run at 30-50 FPS, even with settings at medium and VSync off and frame limiter off. What is causing this awful FPS drop?
