Flickering Tv-guide and other overlays with EVR enabled (1 Viewer)

not necessarily all that strange. after reading the thread about miroslavs patch, it seems that TVServer puts quite a massive amount of disk-io on the system. although the OS will cache a lot of those and not flood the disk with commands, it may have some kind of influence on a driver level and this could be enough to bring the ATI driver out of its comfort zone.

I have installed miroslavs diskIO patch for about 2 weeks now and still having the problem with flickering gui. So i can´t confirm that!

Well, it was not said that it would fix anything - just in some cases it could give more CPU time for ATI's drivers so the actual issue might not happen as frequently (or at all) on some systems.

For me the problem completely disappeared when switching from ATI 26XX to ATI 5570

here is my latest update on the flickering GUI problem:

I upgraded from onboard HD3200 to HD5470, Win7 32 bit, latest Catalyst and EVR.

I have flickering with PDVD 8 mpg2. I have no flickering with PDVD 10 mpg2. CPU load is similar, I think DXVA is functioning for both.
I have no flickering at all with DXV-accelerated h.264 channels with PDVD 8-9-10 h.264 decoder.

I still think the problem is with the proper application of DXVA. Everybody must test his own setup to get rid of it, finding the "sweet combination" of Renderer+Codec+GFX-Driver+GFX-Hardware.

could you test your HD5570 with PDVD8 codec and MPG2 Television? You can find it in "HD-Pack 2.2" (google). Just for fun.

Went from a 4550 to a 6570 and all my flickering is gone. Guessing that a more powerful gpu can cure the problem.

mr viggo
which one have you buyed?

- since the problem only occurs with dual cpus.

Sorry, I must contradict. I have the problem on a single-core (multithreading) P4.

Hyper threading is same as multicore from the driver / software point of view when it comes to thread scheduling.
