G-Sync and FPS Games

[Interceptor]

Hi
(sorry for my English)
I'm looking forward for G-Sync mostly in FPS games. So far "demos" with g-sync in action was with non-intense videos or games (LoL/Starcraft?)
before buying it (atm it's overpriced, waiting till price drop to around 100$) want to know that it will give me the same comfort as i play right now.
I'm playing Battlefield 4 atm most of the time. With Asus VG248QE@144Hz (i play without lightboost) and v-sync off, FPS around 100-300+ and its just great, of course i play with settings set to custom (mostly low, filtering,mesh and textures set to high) to handle high fps.
Could someone with g-sync and battlefield 4 check is game smooth at 60,120,144 vs 144++ without g-sync.
I'm using MSI Afterburner to monitor whats is going on when i play,
I turned on frametime to show in OSD in-game. I'm not sure is it affect game smooth
60FPS 16ms Frametime i feel like play with slow-mo
120FPS ~8ms way better than 60fps
~300FPS ~4ms hard to feel difference between 120 and ~300FPS.
how it might be with G-sync on @60-144fps (then i could turn on details to ultra and still have the same smooth as @120+FPS)

Right now whenever fps drops under 100 i can feel it.

Getting Battlefield 4 to run at high framerates (100-300fps) is quite impressive, and I must ask a question about how you're managing to get Battlefield 4 to run at 300 frames per second. Are you using a multiple-GPU setup, or are you reducing detail levels massively? I noticed from your screenshots, that you probably turned off shadows, which probably helps your frame rate massively.

I'm about to publish my GSYNC review Part #2 before I go to bed tonight, and it actually covers some of this subject.

I can, however, confirm, via my high speed camera tests, there's virtually no latency difference between VSYNC OFF and GSYNC. Test results are within ~2ms of each other.

Whole chain latency (button-to-photons) in Battlefield 4 is quite high, from button-to-photons, often exceeding 60 milliseconds. That includes game logic, frame buffering, micropacket transmission over DisplayPort, and visible pixel transition. I have soldered a LED indicator to the internals of my Logitech G9x, and pointed a 1000fps camera at both the mouse & the screen, measuring the number of milliseconds between button press and illumination on the screen. It is known that the whole-chain input latency is quite complicated, as known from AnandTech's Exploring Input Lag Inside & Out

...versus...

So check again in less than 24 hours, and you'll see GSYNC Part #2, with these input lag tests!

thx for reply
im using single gpu [email protected][email protected]
of course im not saying about constant 300fps(probably 100-150). and yes most settings are set to low to keep fps over 100 (FHD)
gonna wait for GSYNC part 2! than.
Cheers!

I'm running SLI 770s and a 4770k OC'd to 4.5Ghz and I have most of my settings on low but I have lighting and filtering on medium.

I rarely dip below 120 and sometimes I get in the 300s too. On the test range I get a pretty consistent 200 FPS.

Battlefield 4 is high on my list of games to test once I get my G-sync kit. I only have a GTX 760 but I'll see what sort of framerates I can achieve for testing. I've been getting ~45-90 on high-ultra settings which is perfect for G-sync testing but I'll see what I can get on low.

if u could test low settings with 100++fps vs ultra at 50-90fps.
right now when i play at 100+fps and when it drops under 100 it's noticeable to feel lower smooth of gameplay.

Go check it out now.

G-SYNC Preview, Part #2

Covers two big topics:
- Actual input lag measurements of G-SYNC!
- ULMB (Ultra Low Motion Blur).

i already read it, and thats what im looking for, v-sync off vs g-sync on with the same fps looks good, but how it will be compared with high fps (settings set to low) 100++ vs g-sync on with ultra details and fps around 60-100
it might be the same as cs:go(300fps v-sync off is equal to 120fps g-sync on) but game engine is different and just wanna be sure
anyway great test, looks like huge step made by nvidia for smooth gaming

I would like to see more latency tests.

Blur Busters is looking for readers/players willing to do this lag testing for blur busters, using my method invention. It simply requires a simple gaming mouse modification and a cheap 150 dollar high speed 1000fps camera. Beginning this year, Blur Busters will pay blog reporters (per article or agreed round of tests) for exclusive article content written for this site. If you have blog writing and game testing experience, send me a pm.

Just ordered the upgrade kit, definitely interested in doing some testing with BF4.
