FreeSync/G-Sync Compatible Input Lag?

A new video examining the recent addition of NVIDIA graphics card support for adaptive sync on some FreeSync monitors reveals some unexpected issues with this (thanks [H]ardOCP). The video raises concerns that this invokes added input lag in some cases. Here's word: "What did look like a fast and straight forward test turned out to be quite a challenge which lead to some interesting results and raised more questions about adaptive sync monitors on Nvidia graphics cards."

Not unexpected at all. Freesync monitors pretty much always have worse input lag than their G-Sync versions (and other limitations). You cant magically make them as quick as G-Sync ones, nor should you expect that software conversion doesnt add more input lag.

I will continue to buy full G-Sync support monitors instead of the inferior versions.

My ASUS panel is 3 years old now, but at the time the exact same panel cost 30% where I am for the gsynch version. Same refresh rate range, response time, quality, all that.

Same power video card from team green cost 30% more as well.

No, it's not as good, the card runs hotter than the Nvidia one, freesynch only works at 40-90 fps (Which is where all my games run at QHD anyway) but a 30% premium for a slightly more polished product? No thanks. I spent 1400 AUD total for screen and GPU as it was. I'd consider getting NVIDIA on my next upgrade if they could run freesynch as well as my radeon does, but apart from anti competitive nonsense I don't see why they couldn't have been doing that for years already. Perhaps the low sales have convinced them to play ball and try and open up to customers like me with a lot of pennies sunk in displays lacking their fancy expensive chip.

I picked up a freesync-2 monitor after the announcement, and it’s worked fantastically. If there’s any input lag, I haven’t noticed. Nothing I’ve played has felt like there’s any noticeable input lag. I AM over 40, though. Maybe *I’m* too slow to notice.

If you have it set correctly it's as good as Freesync has been. I think it is if you don't have that setup the and settings the drivers could be problematic to more lag?

I have given up on waiting for BIS to come back to their senses and do a real ArmA 2 successor.

Nah, probably just too smart...;) Us over-40 folks are immune to sensational "journalism" *cough*...;)
It is well known that I cannot err--and so, if you should happen across an error in anything I have written you can be absolutely sure that *I* did not write it!...;)

I thought I was getting slower (44) but I tried a reaction test online then got a couple of my teenage kids to do the same. I'm still faster than one and the same speed as the other, so I've stopped making excuses now.

Self-belief helps even in games - don't let the maybes creep in.

Saw that last week, at 13:57 it shows a graph with all the details. If you have a compatible system they are roughly the same between makers, you would run it vync off and gsync compatible on. If you don't have a compatible system, run the slightly older driver until this is sorted out.
