Hi all,
I am having some issues with my new BI setup and would be curious if anyone has any insight. - Here's my situation:
I have a new BI build with 26 cameras. I had BI for 5 years with 20 1080p cameras and it worked fine but since I was going to 2560x1440 I rebuilt it with way higher specs, but it still have issues with lag/freezing in live preview.
Specs:
CPU: Intel i9-9900k
RAM: 32GB DDR4
SSD: Samsung 970 Pro 512GB
Cameras:
BI settings:
One thing to note is that I'm not interested in using substreams. I tried that and just am not happy with the performance - Plus I don't think it's a processing speed issue since my RAM now sits at 15-25% and my RAM is only 25% utilized.
From all my troubleshooting, this LOOKS to me like a live preview graphics issue. I'm connecting a 2560x1440p monitor directly to the motherboard and using the intel graphics on the i9-9900k - What I'm wondering is would my situation be resolved by getting a GPU just to power the monitor off of? And if so what GPU would be recommended if I'm just using it for live preview?
Thanks for any insight!
