Hi, I have had my rig for 5 months and haven't had any problems up until recently. It has a 9700k and a 2070 super in it with 16 gb of ram and an ssd and hdd. In games, I hve been getting random microstutters that I have never had before, and it gets really annoying especially in vr. Also, lots of games won't launch and tell me that d3d device has been lost. I don't have an antivirus to interfere with it and I'm on the most recent drivers. I don't know why any of this is appening. The only things I have downloaded are steam and other launchers, chrome, and beat saber maps. I don't understand why my computer randomly starting to run slower. Also, I get issues where my mouse will freeze for a few seconds and then appear where it should be. Any help is appreciated.
