Poor capture quality

Hi all Looking for advice on my set up. I stream from an iMac and due to its age I capture devices via another machine. The iMac has usb 3 ports. Quad core i7 3.1ghz 16gb ram. Obs 29 on Ventura. I capture bc one I use an iPad sculpting app and two because my streaming machine isn’t adequate for blender. I’ve tried lots of settings and reinstalls and even 2 cap cards and swapped them around. Both cap cards produce expected quality on a friends pc. Eg it looks like the system display I’m using resolution wise. Basically, what obs is doing im not sure but my 1080 in looks like 720 or maybe less tbh. If I preview what’s coming in with quicktime on the iMac it looks fine. Sadly I can’t port qt to obs though as obs then has massive frame drop. Any help appreciated. Image linked. Blender is being captured and the avatar etc not. Image
