You have a GeForce GTX of some form that actually slows down when you change the quality setting? Wow, just wow.

nah,its just cause i have low ram(4GB),and a powerfull motherboard,the card it self requirs atleast (4GB) at maximum processing so it will lag,so yeah.
Probably shouldn't be using RTRT... Even though it wasn't made to be played with.

Sometimes,it just lags for unknown reasons tho,plus some of the GTX cards were made for gaming and 3D,AMD too.
