What should my target frametime be?

[VileAngle]

Hi all!

I upgraded my CPU earlier today from an AMD-FX 6300 clocked at 4.2 GHz to a Pentium G4560 that I got with a promo for $60, on a flash sale.

I run at 72 Hz (I overclocked my monitor, I love to tinker!), and was wondering what frametime I should be shooting for? I know that for 60 FPS, I should shoot for 13,3 MS, but how about 72 FPS?

P.S if I cannot maintain that frametime with a reasonable margin of error, should I cap myself at 60 FPS to eliminate issues with bad frametimes and stuttering? Or is there another way to solve the issue?



Specs:
Pentium G4560
8GB DDR4 2400 MHz (will be 16GB, as soon as I get my other stick of RAM in)
GTX 1060 6GB (yes, I know that this is a very OP card for the system)
10800 RPM HDD

I seem to have answered my own question.

The correct Frametime for 72 FPS is 13.8 MS.

As for capping the FPS, I've found that capping with Rivatuner at either 60 or 72, depending on the game, gives a better experience than 72 at a variable frametime.

Good tips for anyone that's cpu bound like me. Cheers!

Also try fast sync from nvidia control panel instead of vsync,without any capping on games that are well coded it will be an even better experience then being capped at 72.

What exactly is fast sync?

Is it a more optimized version of Vsync? I've always heard to leave it off.

Reguardless of what it is, I tested it in a few games, with pretty good results.

In Portal, fast sync gives a solid 5.2 ms at around 150-160 FPS, which feels really smooth. But... 72 FPS capped and 13.3 ms feels just as smooth.

Borderlands gives me a mixed framerate of anywhere from 80-200+ FPS, but maintains the correct frametime with the framerate. I.E. As the framerate drops, the frametime seems to go down with it, and vice versa. No stuttering to be found. But, again... it felt the same as 72 FPS capped.

I also tested it out in Tomb Raider 2013, just for giggles. This is one of the very few games that pegs my GPU at 100% (ignores my CPU bottleneck completely!), so i was thinking maybe that would change things. I get anywhere from 75-130 FPS in the area that I tested with Ultimate settings, with a frametime that, again, adjusts perfectly to fit in with the framerate. This game actually feels a bit better with fast sync on for some reason. It may have been a placebo, or maybe something was going on in the background, but the camera and some of the fast animations in the game felt a bit jerky with FPS capped.

It's like running the game without any sync meaning that the game will run as fast as possible,but it still retains sync meaning that it will only send finished frames to the display.
Bottom line max fps without tearing.

I've always heard to leave it off.

I'm sure there are combinations of hardware where it will run worse or cause problems blanket statements are stupid,try it out, if it works for you use it if not turn it off.

For competitive gamers that's a good increase in response time "lag" without ill effects.

Considering that I have little to no issue with input lag, and play very few competitive games (I dabble in E-sports from time to time), wouldn't setting fast sync to on be pretty useless? I feel very little difference in most games, and by letting the game run at a high framerate, I'm just putting strain on my hardware that could be avoided.

Yup pointless for your purposes,you could even have left the display at 60Hz,but it's cool and good to know, you never know when you might need it.
