martenmy net_graph says im on around 50 on a pub, but it felt so smooth. How is that possible?
There's a difference between frame times and frame rate.
Frame rate is generally the average number of frames rendered per second. However, each frame might be slightly offset from the others. In an extreme case, let's say the first 50 frames take 10ms each. That's half of a second, and you've rendered 50 frames. However, then suddenly your CPU is heavily taxed, and the next 10 frames each take 50ms to render. You've rendered 60 frames in a full second, and the frame rate counter will display 60fps, but because of the huge gap in frame times, you're going to notice stutter. It won't look smooth.
My guess is that all of these old broken cvars caused horrible stuttering and unnecessary CPU stress, which in turn would increase frame time variance, decreasing smoothness.
