Vsync enabled = lag?

[andy1992]

I play the game (hfl2),everything on high inc AA and AF and receive around 250-300FPS.

Turn on v sync and as you would expect the frame rate is capped to my refresh rate = 60FPS. However the game lags like hell even though im getting 60 FPS, feels like slow motion.

What is the problem?

Disable vsync. Simple :D

Try turning down AA to 4x.

I got a frame/ps at around 380 when v/sync was off... Then it returned to 210-218 when I re-enabled it. Sometimes goes down as low as 170. Except Ep2 where the portal storm really tales its toll and drops it to ~80 which is around my refresh rate on my monitor (CRT - can't afford a newer one yet)

WOW that is very strange, turned the AA down to 4x as spirochaete suggested and it eradicated the problem, even though the frame rate is exactly the same at 60fps.

That is very strange, why cant i do both?

Id rather have v sync enabled as not only does it rid the screen tearing but your not wasting 75% of your FPS as your display cannot display it.

How did you record that high of an fps, Fraps is capped at 300.

BTW, i contacted HIS about this and they said that my card was DRM and that i should return it.

I have v-sync issues in every game that utilizes it. I have accidentally enabled it in Source games a few times and it gave me nothing but problems.

i've had issues with 6x AA too for some reason. I have a high end rig, but 6x AA just doesn't seem to want to cooperate in HL2. i don't get lag like you, but it doesn't seem to smooth out the jaggies at all. 4x AA looks much better for whatever reason

I use the in-game permanent overlay which gives me a clock and fps reading that always updates pretty quickly
