If I knew how, I would have done it already. The driver seems to have an integrity check somewhere that causes DXVA to break with any change, and I don't know how to get around that.

DXVA has never worked with the patch. 14.4 is the only version that allowed videos to play with DXVA enabled, but I'm not sure if it was actually enabled or if it was just falling back to software. I didn't find any evidence that DXVA was actually working.

You shouldn't have to disable hardware acceleration in Chrome. That will cause performance problems. Disable hardware acceleration in the Flash Player settings only.

It shouldn't affect audio, and the K-Lite codecs are just an easy way to get most videos working without having to configure anything. There's probably a way to get bitstreaming working with K-Lite or some other method.

Does it work correctly with the patch at 60 Hz? The patch shouldn't affect CrossFire like that. It may be a separate driver issue that I can't do anything about.

Get NVIDIA cards. People have too many weird issues with CrossFire.

I did not use the Pixel Clock patcher yet but only CRU for now. If I add a custom resolution with 70hz and reboot I can select 70hz fine and it works perfect, now adding anything over 70hz, even 71hz doesn't even register in Windows. I tried adding 70, 71 and 75 with CRU and when I go to the Hz dropdown menu on Generic PnP Monitor everything above 70hz isn't listed even though CRU still has them listed as inserted. I used LCD Standard as my preset when adding 70hz, 71hz and 75hz.

I assume this means I have to use the Pixel Clock Patcher?
If you can use an HDMI cable, you might be able to get around the pixel clock limit without patching the driver by importing the hdmi.dat file.

- I lose Flash hardware acceleration (I have that disabled anyway as it annoys me that my GPU clock gets stuck at 501mhz whenever a Youtube tab is open while not even playing)
Yes, but that shouldn't cause any problems.

You should be able to use the Gaming Evolved app.

Yes.

I'm not sure, but accelerated encoding works in some other programs.

It doesn't matter with most monitors.

RE: AMD/ATI Pixel Clock Patcher
Hey, I was wondering since the new 14.9 driver came out, does this patcher work without any issues for an r9 290x? I tried to install this patch a few days ago, and everytime i watched a youtube video my video would really lag, and freeze, and I would have to stop the video. Any flash video it would do this. I rolled back the driver and repatched it and I did not have this issue. Any ideas?

If it works at 60 Hz with the patch, then it's not a patch issue. I really can't do anything about driver issues like that.

You shouldn't have issues with Flash videos if hardware acceleration is disabled in the Flash Player settings. If you're using Chrome, do not disable hardware acceleration in the browser.

If you're still having problems, try repatching with 1.3: https://www.monitortests.com/atikmdag-patcher-1.3.zip

I feel tied to using Catalyst 14.4 with Pixel Clock patch 1.2.4 because I really need DXVA support. I spent the last couple months using 14.7 with 1.2.6/7 and all the hardware video processing issues have been a total nightmare.
14.9 seems to have fixed the blue screen problem, so I can remove the workaround and restore the behavior from 14.4.

Try repatching with 1.3: https://www.monitortests.com/atikmdag-patcher-1.3.zip

You still shouldn't have issues with Flash videos regardless, but that might help with the other issues.

Toasty you're a bloody genius! Thanks so much. 14.9 + 1.3 works perfectly.
