Is this true? Is this why the game doesn't have the "creamy" feel to it that you get at 60 fps? Also, does anyone know how to display fps in game?
no, in fact I have 70 80 fps myself, if you're stuck at 30fps then it's because your v-sync parameter is on, and your monitor is refreshing at 30Hz.
Just disable it and your game will run faster but since your monitor won't be able to refresh it at this rate, you won't see any difference visually.
For a quick reminder, all competitive games, even console ones, try to approach 60fps as it is much smoother in response time when the game engine is fps dependent.
This is why often halo or gears of war won't be in 1980p but upscaled.from 600 or even less.
When you have a slow machine you won't sacrifice fps for aesthetics purposes, you'll sacrifice textures, post-process and resolution to aim at a good framerate.
