Preview screen tearing issues with new RX460

kplo schrieb am 11.04.2017 um 21:32 Uhr

Hi all,

V 11 (32bit) and V 12 (64 bit) are both showing tearing on the preview window with my new Radeon RX460 card (4GB model).

My footage is all progressive...a mix of Canon HD 1080p 30 and DVX widescreen 30p in this particular project. Editing on a 1280x720 29.97p timeline for web export. Same setup I used on my ancient box with a Radeon 8500 card (no issues there). Tearing occurs with vertical and some horizontal pans on original files, Cineform and Sony .mxf renders. This happens with GPU accelerated processing on or off in preferences. Separate system, video data and render drives, all WD Black 1TB versions.

There was a several year old thread on this with Nvidia cards and no solution at the time.

I updated to the latest Radeon drivers. The old reliable Catalyst package has been replaced with "Crimson" software...maybe that's the problem. I have changed the refresh from the stock 60hz to 72hz (my Acer monitor can supposedly be overdriven to 75hz) with little change. The preview looks fine on my old CRT external display with firewire through the Sony deck.

Is anyone else experiencing this with the Radeon RX400 series cards? I'm thinking my i7 6700k CPU,16GB Ram, Win 7 Pro and this card should certainly be enough to handle this. The issue also occurs when playing clips in Windows Media Player and to a much lesser extent with VLC.

Any help with this frustrating problem is much appreciated.

Thanks,

Ken

I have an RX480 8GB card and haven't noticed a particular problem. How is your monitor connected, VGA, DVI, HDMI, Display Port?

Thanks for responding John. The monitor is connected with HDMI. Used the cable that came with the monitor. Swapped it out for a new HDMI cable just in case, but no joy. What settings are you using with the Crimson software? Perhaps I have something set wrong. Under the Video tab, I chose "Cinema Classic" because it looked the most neutral with my footage and didn't over sharpen it.

I have the 8 gig version of that card and so far no problems (i7700 processor).

I have a 290 and run 4k material without tearing (mostly).  There is a "wait for sync" switch (checkbox)  on the Vegas preview device setting that may help.

Thanks folks.

Rolling back driver to older version didn't help. I don't have "wait for sync" checkbox in my Vegas preview device, but I did activate it in the Crimson software prefs. Seems to help a little bit. I notice that the first time I play a clip I get the rolling/tearing artifact, but the next time the shot loops, it's much better. Maybe better buffering at that point??

Anyway, thanks for the info and suggestions.

Ken

Well, it seems that setting the refresh rate in the AMD Crimson software prefs wasn't really changing the monitor refresh rate. Downloaded a little program called "cru 1.3" and was able to change the refresh rate to 75hz, which has pretty much eliminated the tearing issue. I also set the "wait for vertical sync" to off on the RX460 prefs.

Only VLC would properly play the clips with the old 60hz refresh rate.

Anyway, problem resolved.
