Choosing refresh rate

[NomNom]

Can you please make it so we can choose our in-game refresh rate instead of us having to use the default windows refresh rate all the time? An option to disable vsync would be nice too, I'd like to have 100fps in-game like I do with all other games. Maybe there's already an option to change your fps cap manually that I don't know about?

You do realize that the human EYE only works at 60 fps, right?

You can disable vsync with a console command:

Press F1 to open the console, then type
vsync false [enter]
To disable vsync (vsync will remain disabled until you manually turn it back on using the console).

To increase the refresh rate to 100 you can use the console command:
testTargetFps 100
(The target FPS will stay at 100 until you exit the game -- we will add an official, persistent version of this command soon)

I played fps' competitively for years and believe me there's a difference between 60fps and 100 fps, very small but very important nevertheless. There's a reason why CRTs are still used for any competitive games.

Yea I tried testtarget 100 but the indicator on the bottom left still said 60fps.

You need to disable vsync in addition to using testTargetFps -- depending on your video drivers that may only be possible in fullscreen mode. You may also need to change your driver settings (OpenGL -> vsync -> always off, or use application setting).

The human eye doesn't work on frame, but most people can actually recognize upwards of 100-200fps and maybe even higher, depending on lighting conditions. There was a really awesome website demonstrating this with flash animations, but I can't seem to find it anymore. i'll keep looking.

Coincidentally, do you have a monitor that can even refresh that fast? Because disabling vsync is useless if you don't.

And do you have any idea that it makes a difference or have you just convinced yourself as such?

The human eye might be capable of seeing 100-200 frames per second, but over half of those are blurry and automatically deleted by the eye. That's why you don't really get motion blur in normal life.

Try this: look at one wall, then flick your eyes (but not your head) as far across your visual spectrum as possible. Did you notice the brief flicker? That's your brain automatically removing blurred "frames."

Altitude at 100 fps would likely be going too fast to make any difference whatsoever, plus 60 fps is perfectly satisfactory, you number whore. :P

Coincidentally, having played at 250 FPS on a good quality (admittedly LCD) I can tell you there's no difference whatsoever.

it's moot whether or not he can actually see the difference. It's pretty clear there are advanced users who want to configure refresh rate so we are going to add a command line option to do just that.

On a side note: I had an old CRT monitor that would give me massive headaches if it didn't run at 85hz+. So if he's using a CRT I can completely understand.

I was just about to ask why I was stalling at 50 with a decent laptop. Thanks for the good information.
