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.
