I find this this very handy for video projects which involve nvidia cards. Imagine if you need to know if the card support a specific codec, resolution or even hardware encoding or decoding, this is a huge timesaver.
One caveat is to double check forums and other reports/driver info as sometimes support is listed but may not be present in specific driver versions or OS's (eg. sometimes h265 is supported in the Windows driver but not Linux).
This is one area that Nvidia is quite poor at whereas the amdgpu driver even with onboard GPU/APUs may often support encode or decode that some nvidia cards or driver versions do not support.
