Photostory Deluxe Version 20.01.62
My old PC really struggled with full screen preview of a photostory deluxe project and even at 1/2 resolution was unbearable to watch. So I upgraded to a new pc with B560M AORUS PRO AX (U3E1) Motherboard, 32gb RAM, 11th Gen Intel Core i7-11700 @ 2.50GHz CPU, GeForce GTX 1660 SUPER Graphics Card. Imagine my dissapointed the first time I used Magix and ran a project preview at full screen. The playback was more jerky than with my old tired and low spec PC. Well I played with Magix display settings to no avail, even at 1/2 resolution playback stuttered, stalled and jerked about and was almost unusable (My very old PC was quite reasonable at 1/2 res)
I made sure all windows updates, software, firmware, drivers etc were up to date but still the problem was there. By luck I came across Windows Graphics settings and found Windows GPU Hardware Acceleration was turned off. Turning this on fixed the problem almost 100% although there are some zoom/pan images it still jerks a bit with but its quite acceptable now. I went back to Magix display settings to try and further improve the slight stutter but I have had to resort to Compatibility Mode.
At least its very usable now but PLEASE if anyone has any further advice on the subject I would be very gratefull
I have attached screen shots of the settings I found seems to best suit my PC
