Why? Please tell me where I can get FCPX in Windows?
True....but guess who was the person posting random information from sites trying to prove us wrong about performance deltas? You.
And it is helpful for people in the video business to know what they are working with, FCP or other. This hardware or that, that OS or this, this beta driver or that proper driver.
For example, I created an h.264 encoding test a year ago for the fastest 12 core cMP. I performed the test on this forum for live feedback. The test was to see how CUDA and OpenCL performs on a cMP in OSX and Windows using a GTX980.
I ran the same apps, same settings and performed the OpenCL tests while waiting for the Mac CUDA driver to arrive.
OS X took 2 minutes to complete the encoding. Windows took 30 seconds.
We were puzzled how could this be. I then ran the test again on Windows using CUDA. The time was exactly the same.
One forum salesboy who sells these overpriced cards to Mac users was confident that the Mac CUDA driver was going to speed up rendering. This is a guy who claims to advise many studios.
But he was dead wrong. Because as the discussion progressed a very well experienced video professional joined and let us know that Maxwell cards won't encode to h.264 because they are horribly inefficient versus a CPU for this task (it's a ROPS thing).
In other words, disabling CUDA and OpenGL made no difference. Windows was 4 times faster than OSX purely because the operation system supports Intel's CPU video encode features better.
The video card salesboys didn't know this stuff, they are only good for telling people to buy GPUs that mostly don't live up to the performance promised by them on OSX. When it comes to the nitty gritty details of how real world apps work or how drivers are built, these guys are clueless and they prefer if customers didn't know such stuff.
That's why you need people on this forum to tell you how things perform universally in other apps and platforms , otherwise you'll end up misinformed and having parasitic people trying to empty your wallet with overhyped GPU, USB3.1 and PCIESSD upgrades that don't live up to their marketing promises.
The bottom line is, if you're using FCPX you should be using GPUs Apple has optimised for instead of buying a GeForce card running on a flakey web driver which Nvidia says only has beta support for Maxwell.
