OK, with swapbufferswait off, vblank_mode=0, and added glFinish, most of the
time is indeed spent in glFinish, up to 60ms.

glClear takes on average 110 us, with the highest being 2.6ms. Still high, but
not alarmingly so.

I suppose this means the card is just that slow?

PS:
On the files, last time I tried to attach apitrace output here I hit a size
limit...
