The AMD Driver Thread

[africanos23]

The pro drivers would be best bet as you'll want openCL at a guess.

Yeap perfect, thanks for digging deeper.

Ok, I've re-installed the driver twice and still freesync will not work in Mafia 3. I'm averaging 60 - 70fps and it's just a screen tearing mess. After redoing the driver FRTC works fine now and all but freesync still no bueno. I've reported it but was hoping maybe I was doing something wrong

Every other game fsync works great. GOW4 ftw

I have no idea what's going on there mate. But Freesync definitely working on my pc with Mafia 3

Just in case, have you made sure the game is running full screen and not full screen windowed mode. I have had a few games over the years put me in full screen windowed mode for no reason. This would disable Freesync.

Does freesync work with dvi(pc) to hdmi(monitor) cable, because if I use a straight hdmi cable, I get nothing on the screen before windows loads.

I take it you using a monitor with HDMI Freesync? Does Freesync show up inside Crimson drivers?

Yeah, as my monitor doesn't have dvi connection. It says its enabled and turned on in the Crimson drivers when I turn on freesync on the monitor, but its still tearing when I turn off vsync?

 

[something daft already!!]

Thank goodness they removed cRaptor from the install media. Sometimes I forgot to untick it and had to nuke my PC from orbit, just to be sure. Well uninstall it anyway.

Is your frame rate within the freesync range? What monitor is it?

 

[Phil2008]

I think with freesync enable, the refresh rate goes up from 60hz to 72/75hz https://www.overclockers.co.uk/sams...creen-lcd-monitor-silver-white-mo-22o-sa.html

OK you will need to keep your frame rate for this monitor between 60fps and 72fps for freesync to do its thing.

The best way would be for you to create game profiles inside Crimson for the games you play with a max FPS of one below the max refresh rate so 71hz


OK also just found this write up about this monitor Freesync. It has two modes

There are two FreeSync settings: Standard Engine and Ultimate Engine. Standard Engine enables FreeSync between 58Hz and the monitor’s maximum 72Hz, while Ultimate stretches the bottom limit to 48Hz.

This means that if you have a mid-range graphics card that struggles to hit the screen’s 72Hz refresh rate, FreeSync will help provide smoother motion and less tearing as long as the frame rate stays above 48fps. With some experimentation, I was able to tweak the settings of my favourite titles to not dip below this magic point, gaining smoother motion and eliminating tearing, even though my graphics card wasn’t able to output enough frames per second to match the monitor’s refresh rate.

Thanks for finding that out, I will have to try a straight hdmi cable and see if I can get it working, but its a pain as the hdmi socket on the gfx card won't display the bios or the post before windows.

Give DisplayPort ago I believe that Monitor support both Hdmi and displayport Freesync. Double check though

I think you only have fullscreen on or off in this game I've tried alt+enter to go out and back in fullscreen (works on mechwarrior online) but no change

 

[nashathedog]

Freesync will never beat Gsync, as it's still limited to Fullscreen only mode.

Gsync can do it's magic in Windowed, fullscreen windowed and fullscreen exclusive mode.

Except that article more or less has just stated that it has

They also forgot to mention that intel will be supporting adaptive sync as well as support coming to TVs + consoles

Someone posted figures for g vs free sync selection:

2015 G-Sync monitors: 8 IPS, 3 TN, 1 VA
2016 G-Sync monitors: 3 IPS, 5 TN, 6 VA

2015 FreeSync monitors: 13 IPS, 15 TN, 2 VA
2016 FreeSync monitors: 32 IPS, 17 TN, 13 VA


Not bad considering gsync was out for over a year longer.

Only a matter of time till AMD add support for windowed mode etc.



Yup, it is only a matter of time till nvidia add the support and make gsync even more niche than what it already is

The number of monitors available is all well and good but it's the working range that lets a lot of free-sync monitors down, As a rule the companies making the monitors choose the panel and parts and too many free-sync monitors have poor ranges unlike G-sync one which tend to stretch from 30 up to the monitors max. I had an Asus Dominator temporarily which has a 144hz panel but the free-sync range was only 40 to 90 and that's one of the better 16:9 IPS models. So unless I limited the fps to 89 via software I was constantly getting an freesync is turning off message appearing on screen. I now have a 75hz 21:9 panel which has a working range of 35 to 75 which is a lot better in my opinion and one of the better 21:9 panels as a lot have rubbish working ranges such as 48hz to 60hz (that's a worse case example from LG, what were they thinking?), So yes there is a lot more Freesync panels but a lot of them aren't worth getting if that feature is your target.

Basically you have to be very careful when looking for a freesync monitor. There are good ones it's just a matter of finding them and sometimes finding out what a monitors working range is can be next to impossible.

Freesync works perfectly well for me in fullscreen bordeless mode with recent DX12 titles (Battlefield 1, Forza Horizon 3, Deux Ex Mankind Divided,...)

Also, for those of who of you who might have problem with Freesyncs I think the explanation (from an AMD guy) below will be useful:

[–]AMD_RobertTechnical Marketing 4 points 1 month ago*

OP, I see you're using FreeSync and FRTC together. Don't. The FRTC algorithms that analyze frames to reject useless ones can interfere with the rolling frame time analysis performed by FreeSync to synchronize the display with the GPU. If you are using FreeSync, your FPS is being capped anyways because you have vsync enabled alongside it to pull the FPS back down when it exceeds the DRR range supported by the display. And if you didn't want vsync enabled to contain the framerate to the DRR range of the display, because you cared about the lowest possible input latency, then you wouldn't be using FRTC.

//edit for clarity: If an app's FPS is within the DRR range of a monitor, then the FPS vs. Hz will be synced 1:1. The vsync setting matters for what happens outside of the DRR range. If vsync is on, then the GPU will simply reject frames to keep you within the DRR range of the display if the FPS tries to go above the range. If vsync is off, then the FPS can go however high it wants and you will get input latency benefit at the expense of marginal tearing. FreeSync will resume activity if the FPS falls to the DRR range again. Below the DRR range of the display, LFC is active if the monitor supports.

In both cases, FRTC is undesirable and unnecessary in the presence of FreeSync.

https://www.reddit.com/r/Amd/comments/4z2spv/fix_freesync/?st=iuicx2mf&sh=ed9bcd66

I personally used to have issues with Freesync not working on some games when I was using it with FRTC, since following the recommendation above I no longer have any problems (R9 Fury + Asus MG279Q).

I'll have to revisit this but i'm sure when i ran Dirt Rally VS + FS with no FRTC i got tearing. With FS and FRTC and no VS it cleared up.

Since then i've always run FS + FRTC and no VS on everything, can't say it felt or looked 'bad' as a result.

I'm having issues getting the softwear suit to show on my system. New build, spec in sig using win10 pro.

The drivers are on, crossfire seems to be working but no interface so no goodies. Can't get my 3rd screen to show and my seccond screen seems to be limited to 1080p, no 1440p option in windows. Any ideas, anyone?

 

[shankly1985]

I notice no difference between using vsync or FRTC even AMDMatt disagrees with Robert here..

I still feel AMD should release an official statement on Freesync. Am even hearing people say enable GPU scaling gives better freesync than using display scaling..
They is just so many questions around Freesync that AMD should answer.
