change your renders in options, DirectX to OpenGL or the other way around, then try to cap your fps or set it to unlimited.

PC specifications?
What do the numbers look like? (When you get frame lag at the start of a map and when it runs smoothly/)
When did this issue start?
Also what does your GPU & CPU usage look like when this happens? (Test this with MSI Afterburner.)
What if you pauze the song right before the 1st note and then upauze a bit later?
More information please, As it stands right now It's like trying to find a needle in a haystack.

If I pause the song for a little while and then resume (I tested this yesterday) it has no effect and will lag at the start oblivious.

Framerate numbers.
When playing you get about 500fps. When you get framelag on it would drop down to about say 90fps. For example.

GTX 570m I guess that would be.

And what happens to the usage levels when the lag kicks in? Does one of them spike up? Or does it drop down? Or does something happen to both?

Allright. Well, a few things I can say;
-Make sure the power balancing is set to maximum performance in both windows and your nvidia control panel.
-Set a "performance" preference in your nvidia control panel (potetially more framerate and less input lag).
-Make sure your temperatures are fine (ie it's not overheating).
(Though this shouldn't be an issue as the lagspikes are obviously not causes by thermal throttling.)
-Use DirectX as renderer with unlimiated framerate, preferrably.

I doubt any of that will make a difference though as it all points towards a software issue from what I can tell.
So yeah, additionally you could try to either update or downgrade your GPU drivers.
Also disable any on-screen overlays (such as FPS counters or temperature monitoring) if applicable.
You could also try setting the priority of the osu.exe process in the task manager to "high" (right click -> set priority)
Also, does this happen on both cutting edge & stable release streams?
Also try windowed mode or fullscreen mode (depending on which one you currently use).
You could even go as far as trying a non-aero windows theme.

TL;DR - Seems really random. Listed a bunch of stuff you could try and see if any of it makes a difference,
though I doubt it will.
Pretty clueless as to what it could be and how to fix it. Likely a software issue,
as if the GPU has trouble drawing the hitcircles and other objects when playing for a bit, and then finally 'catches up'.
