As far as I know ‘there is no difference’, it’s just the release schedule.
Fixes / improvements that appear in the game-ready-driver will also show up in the studio-driver, and vice-versa.
It will not ‘mix settings’ or whatever it’s said in this movie.
It’s just, if a brand new game comes out with ‘experimental fixes / improvements’ for that game, there will be a new game-ready-driver. But they will not do a studio-driver because there is no new studio-level software.
The same the other way around.
What’s wrong in this video, is the toggle he highlights, only is in effect when checking and downloading new drivers. It will NOT switch the driver instantly to the other one. It will only affect which version is used for checking for new drivers, and which you want to download.
But, like I said, there is no real difference between them. The only difference is ‘oh, there is a fix for DxO and nothing else? We will make a new studio driver and we will not bother the gamers’.
‘Oh, there is a brand new game coming and we have improvements for it? We will make a new game-ready driver, and the studio-folk who do not care can just ignore this update’.
But whatever fix they did for DxO in the current studio driver, will be included in the next game-ready-driver.
Or, to say it in other words: There are no two drivers, there is only one. There is only one version number. They just label it ‘a studio driver’ or ‘a game driver’ depending on what kind of fixes/improvements are in the changelog.
