Google how to stop Windows from installing drivers.
Now run Nvidia's GeForce Experience and install their latest.
One of my cousins gave me their ROG GL553VD since he was getting a better computer as he moved out of Canada. I saw some reviews on YouTube and saw that it was a pretty decent gaming computer. It could run Witchers 3 at ultra setting, as well as other games like GTA and Assassins Creed.
The problem I'm having is that I'm running games that are no where near the graphical capacity of the ones mentioned above such as Smite (40 FPS), NBA 2K18, The Sims 4 (30 FPS), RuneScape (40 FPS), etc. For some reason they lag quite a bit while I play and I don't understand why. Sims 4 lags a little bit but not enough to ruin the gameplay. Smite lags and the mouse feels heavy (It's not the mouse sensitivity). That one is weird since I ran it when I first got it and it ran perfectly on the highest settings. Now it's slow and laggy on low quality. Same for NBA. Oldschool Runescape somehow lags when I play fullscreen too. I'm not sure what I am suppose to do or what those YouTuber have done. They have the same specs that I have:
RAM 12 GB
Graphics Card GTX 1050
I'm an absolute noob in this department so I'll try my best to answer any questions.
