I am having extreme difficulty in obtaining a smooth playback (movie preview) ….if there is ANY rendering (I only use cross-fades) or any effects at all the video preview simply cannot keep up with the sound

If I switch to the lowest possible quality it just about manages to keep up but is un-usable as I can’t see the image because it is so pixelated

My PC isn’t exactly a low spec machine ….

CPU : 64 bit Intel Core i7-950 Bloomfield 45nm 3.06GHz

Motherboard : Gigabyte X58A S1336 GA-X58A-UD3R REV 2.0

12Gb RAM : 3 x Crucial CT3KIT51264BA1339 @ 4Gb

Graphics : GF GTX 460 1GB PCI-E HDMI SOC

3 disk RAID 0 comprising 3 x WD 500GB Caviar Black SATA-600 32MB 3.5" 7200RPM drives

Power Supply : Corsair Memory 750W TX

SSD : OCZ Vector 256Gb

Windows 10 64 bit

PDR 14 ultimate 14.0.2019.0 SR VDE150720-04

In use the CPU runs about 20% and the RAM likewise so they aren’t bottoming out

What can I do to improve things ?

I have already shifted everything (files, video content, export folder, the project itself) to the blisteringly fast SSD which made very little noticeable difference

Would another graphics card be the answer ? – mine has 1Gb RAM



edit : for some reason it won't let me add the DXDiag file - I click on attachments/browse and nothing happens...
