If someone needs something specific to do their work, they will find a way to get it.
Every single thing between the free version and the studio version is "artificially limited". It's a choice made by BMD. If you want to see a change, you need compelling arguments for it.
If BMD was listening to the last 3 feature requests I saw, Resolve Free would be Resolve Studio in no time. Thousands of people use the free version and do crazy things with it, and some of them switched to Studio to get more out of their hardware. But the majority don't because the software works totally fine.
There are so many other way to use the free version and have the same punch as the Studio version. Proxies, transcoding to an easy to read video format. Wait, Resolve can do that automatically already
And for the question about : Is the hardware acceleration beneficial - The response is yes. It always is if we compare with no hardware acceleration.
it gives them the impression that your software is just slow and unresponsive
That's not totally true, it depends on the specs of the computer used. The first time I used the free version, I didn't see it as slow and unresponsive.
The software is only $300. And nobody needs to buy it to do everything we can do with the Studio version (other dedicated free applications or web services can fill the gaps of some of the missing tools).
It's just my opinion but I don't think it's even a feature request (same with the posts asking for other tools to be in the free version). If we think about it, the studio version is the "main" Davinci Resolve version. Transferring something to the free version adds or change nothing to the software.
