I think the minimum System CPU for TG is a quad i7 around and above 3Ghz. Preferably a newer generation. (Or an equivalent AMD). I actually tested TG on an i3-not latest, i5-not latest and now on a newer i7-6700. An i3 and an i5 can run TG of course but it is not productive at all. The earlier mentioned i7-6700 is kind of okay. You can get things done with it in a reasonable time.
I think PS should not invest any time to test and test and test...with lower class CPUs than an i7 or similar AMD.
I was very productive until last year on a x5450. Again, this software has not changed since 2009. It's inherently a lightweight program. The only quantative variables is actual rendering and RAM for scenes/pops. Which can most certainly see improvements as TG isn't even as fast as other CPU renderers. You can literally decompile this version and TG2 and see it's mainly be built ontop of with new shaders and and little rewrote. All these things do not impact performance of the renderer, or shouldn't, that would indicate the whole framework is falling apart and needs replacement.
Even the changes to the main renderer have improved upon what was available in 2009 in the performance area lol
Again, again, again, again. This is rendering software which is entirely scalable to even running on XP under my phone at a snail's pace. The only thing that is required is time. However, dramatic changes in computation time for simple changes in camera view for PT immediately suggests something is wrong performance wise. Not my CPU. If it was you are admitting the software isn't optimized and somehow has issues with certain CPUs and definitely should have attention as it no way can be asserted it is only MY CPU, but rather a instruction set/architecture/brand issue.
Masking problems with performance is negligent. Take a look at other renderer software, they target a CPU figure a CPU combination that can get the jobs done. Clearly going higher will only provide higher perfromance, but none of these suites focus on workstation tier CPUs lol Inherently it's rendering, and scalable (or there is a problem). Maya, Blender, C4D, Octane, etc, etc, etc, the list goes on. I've seen none that target workstation CPUs, regardless of their CPU rendering. Nor do none of them just tell people to get a workstation tier CPU in support...
I'm not saying TG should work fast on my system, but a clear radical change in render time by 8 hours is insane and hints at some weird oddity, which I'm trying to figure out... We see tray render times a lot, whether by mistake from render settings or something unknown.
Man, imagine working with SGI and complaining that their systems can't handle it cause how long it takes to just process changes let alone rendering (hence render farms...). xD
