My PC seems to be lagging more often since I updated. It used to run GTA 5 smoothly, now all the textures don't load immediately and the game lags a lot. (My PC is an Alienware m15, default customization)
BIOS is up to date. I ran support assist to get the newest drivesLatest BIOS update on your platform? Lag can also come about from some corruption on the OS or the drivers. You should ideally manually install all drivers from the chipset to your audio after a clean install of the OS.
