Has anyone had a chance to test the image quality of DVDs and Blu-rays with an A8-3850? I can't notice a difference during video playback, but I can when comparing screenshots between the A8-3850 and AMD dGPUs; both 3650 and 5770.
I first noticed it when comparing file sizes of screenshots between the iGPU and dGPUs; I noticed a 2.5% difference in the DVD screenshots of Gladiator and a 1.5% difference in the Blu-ray screenshots of Gamer. As a result, I opened up the images in Photoshop and could see that there was a slight difference between screenshots. VA deinterlacing was used for the DVD screenshots and confirmed working correctly. The fact that two different AMD dGPUs end up with the same image quality should mean that the A8-3850 should end up with the same too, when using the exact same frame.
I normally use MPC HC with the Cyberlink Video/SP Decoder (PDVD8) for DVD playback and the MPC Video Decoder for Blu-ray playback and tested with the same version of MPC HC to ensure the player wasn't the issue. I also tested with the latest version of MPC HC, v220.127.116.1177, with the same results.
I'm assuming that it's as a result of the A8-3850 being so new that either the AMD drivers aren't taking advantage of the iGPU or MPC HC isn't. I've ensured that all GPU video settings that could possibly effect video quality are turned off, e.g. Dynamic contrast, Edge-enchancement, De-noise etc.
Does anyone have an idea what the cause of this could be or do I simply have to wait for more mature drivers?
