[ANSWERED] Processing Threads and Multi-core processors in ISADORA v2
I am attempting to build a hackintosh (the new way using PROXMOX) and want to run ISADORA v2 on OS Mojave so I can use a bunch of old 32bit freeframe plugins that have never been updated to 64bit .. my question is a technical one: can Isadora 2 utilizes multi core processors and uses multiple threads?.. I was thinking about getting a serious Ryzen Threadripper 5995WX because I want the fastest system possible that Isadora v2 can take advantage of.. but I dont want to spend all that money if those 64 cores and 128 threads won't even be utilized. Or am I better off with something like a 13900KS which has fast single core scores and higher CPU clock speed. Is CPU clock speed more important than cores and threads? Most of those old freeframe plugins I use are processed on the CPU mostly and not the GPU. Who can answer these tech questions best? thanks so much
First, let me say Isadora is not supported on Hackintosh, so we won't be able to help you if you run into issues.
With that said, the primary multi-threading in Isadora 2 comes via the Movie Playback systems (Isadora 3 added additional multi-threading in the User Interface). So codec decompression etc can utilize multi-threads very efficiently. The scene patching is run in a single thread, so this can be a bottleneck for very complete patches, and/or patches using heavy CPU based video processing. I find modern CPUs offer plenty of threads for media playback, I don't think you will gain much from a massively multi-threaded CPU, but the clock speed will have a direct effect. Personally, I would go for the faster single core base clock speed.
Given that you say you are using old CPU based Freeframes, you will be limited by the CPU clock speed.
