GTX 1080 ti, GPU acceleration on. SLOW render
Hi, I have used Adobe premiere for about 13 years and I have never needed to contact Adobe before but I really can't find a solution this time.
I find rendering and exporting HD increasingly slow with premiere pro cc. I thought it was down to filming AVCHD 50p, using 25fps sequences and exporting at H264 25p. I understand a little colour enhancements here and there and a bit of denoiser, will take longer but really should it take 10 hours to export 90 minute HD video?
My PC is not that bad, I know it's old but its a HP z800, Windows 7 64bit, 96Gb ram 2x Xeon X5690 3.47GHz CPU's (6core) and Nvidia quadro 6000. I thought the only way to improve is to buy a better graphics card.
So I have just installed a GTX 1080 ti which has 3400 more cuda cores than my old GPU. I have installed the latest drivers and have checked the renderer is set to Mercury playback engine GPU Acceleration (cuda). It is still taking between 8-9 hours to export the 90 min video. something must be very wrong but i can't find the answer. looking at the CPU, Memory and GPU usage, there isn't much going on. The footage is on an internal raided pair of drives and output to an internal SSD
I really thought this graphics card would be the answer to my problems but it hasn't. I have searched and looked at all the settings. If i can't find the answer soon, I will have to return the graphics card before it's too late, i can't afford to waste £800 .

Can anyone help please?
