Hi chaps,

Wow!!!!!!!!!!!!!! this is pretty amazing. I changed the setting for V-Sync in the Nvidia control panel to "Fast" and changed the frame limiter in the game's startup.cfg to 120 and went from 60FPS to an average of 90-100 FPS and haven't noticed any tearing!!!. Try it smile

I always keep my startup.cfg read-only as I have other changes such as bloom off that I want to preserve.

Cheers Aces

My rig for comparison purposes - CPU is Intel I7-6700K @ 4GHz, 16 Gb RAM, Windows 10 64-bit, Nvidia GTX-1060 6 Gb.

I'm not saying everyone will benefit to the same degree and as with all these things your mileage may vary as the saying goes but it does increase the FPS substantially on my rig and it's an easy enough thing to change and try out.

Cheers "Aces"

V-Synch selected in-game and, importantly, the FPS limiter set to 120 FPS (not 60).

"Fast"? I don't recall seeing that setting for vsync before.

I have a GTX1060 (Pascal chipset) and it's there in the control panel. I think that it might be GPU-dependant.

I have a 1070 but I'd never looked for that. I'll do it tonight.

I just heard back from one of my squad mates who has a very similar setup to me, he has a 1080 card and I have 1060 card.

"OK I've done the tweak, and running at 2xdsr with 4x Supersampling and got 112 lowest fps and with 8xSupersampling 110 fps lowest. "

Got very similar results in some other games, CLoD, Silent Hunter V, ARMA III and Wings of Victory. Basically any game that is capable of delivering more FPS than your refresh rate, in my case 60. Some games lock the FPS at a maximum of your refresh rate like all Graviteam titles, APOS, Mius Front and Steel Fury so no gains with these. Interestingly Star Citizen doesn't have an option to enable v-synch in the game and used to give me 30 FPS (half my refresh rate) !!!. I setup a profile using this Fast V-Synch and my FPS has now doubled to 60 FPS, this has pulled it up. I'm at a total loss to explain this.

At least I know that I'm not the only one that it works for smile

Cheers

Fast V-Sync is the rendering of frames decoupled from monitor V-Sync, but the monitor will only show "complete" frames, so no tearing. It's like Gsync/Freesync, but monitor agnostic and basically only useful if your frames are higher than the monitor refresh rate (the game physics/input processing will run at full speed, and your monitor will only display at the refresh rate, reducing tearing).

It don't need to sync to monitor full or half rate like normal V-Sync and Adaptive V-Sync, but it won't give more frames in any case. Unless you are playing some twitch shooter like CSGO, running the monitor faster than your refresh rate won't give perceptible results, and will only increase power consumption and dissipated heat.

Hi, It won't give more frames, it will let more frames be displayed compared to traditional V-sync and not tear like having v-sync off would. With v-sync off I get higher FPS but tearing, with v-synch on I a maximum of 60 FPS as it's my monitor refresh rat. with Fast vsync on I get a maximum of 120 FPS and average about 100 FPS without the tearing. I haven't noticed any input lag, my card isn't running hotter (stock cooler). I found this vid which gives a pretty good explanation of fast synch for those who are interested. https://www.youtube.com/watch?v=WpUX8ZNkn2U

As you say it's only useful if the game delivers more FPS than your monitor refresh rate and, for my setup it does.

As I mentioned before, it's something to try. If you have a Pascal chipset Nvidia card then it's easy to try it out. If you like it keep it on, if you don't turn it off, "simples" smile

Cheers

As I like to experiment I just, did a benchmark on an action-intensive campaign mission with plenty of zooming in and panning around in twisting and tuning dogfighting. GPU ran at a maximum temp of 60C which is the same as without Fast-Vsync.

Frames: 55279 - Time: 580000ms - Avg: 95.309 - Min: 65 - Max: 120

So my minimum FPS was higher that the normal maximum 60 FPS v-synch imposed limit and my maximum FPS was double the normal v-sync limit and my average approx 50% higher than normal v-sync.

Cheers

Hi,

As others have said, if it works for you then use it. It seems to me that the easiest way to test is to run a game without any form of v-sync and see what frame rates are possible. If this is substantially and consistently above 60 assuming that your monitor is a 60Hz monitor then there are FPS gains to be made with it on or to put it another way there are gains compared to running with conventional v-sync on which I do because I don't like tearing especially using Track IR.

I just ran RoF, the thing that lowers framerates in RoF for me is supersampling as one might expect. With conventional v-sync enabled in-game then I'm capped at 60 FPS as one might expect with my monitor refresh rate. With fast-sync on then my framerates go to a pretty constant 110 FPS.

Cheers

Aces

N.B Also remember to increase or disable any in-game frame limiter whilst testing.
