How abouts would I go to get the fps using SDL?
If you need more information, please do ask.

Thanks in advance.

Your FPS is the inverse of the time elapsed between this frame and the last frame. SDL_GetTicks() gives you the current timestamp, in milliseconds. Go from there.

Sorry I don't know C# but generally you need to

-choose how often you want to poll fps

-get an initial time variable T0

-increment a frame counter after every render

-assign SDL_GetTicks() to a current time variable t

-check the time passed (t - T0)
if it is greater than the polling time you chose, FPS is just the frames divided by time passed in seconds ( / 1000 because SDL_GetTicks is in ms): that is FPS = frames/((t-T0) / 1000).

-when that is calculated, do whatever you want with your FPS value, set T0 = t and frames = 0

i'm not sure where i got this from, i think it's from a nehe tutorial maybe, i found the same code i'm using in another thread on here
