to much game works , will skip this and pick up dragon ball z instead
You do not have to enable gameworks - assuming the demo is bugged and the issue is resolved for the game.
Did you buy Witcher 3?
For me I want to see if they sort out the performance issues relating to LOD and anything else that is not working correctly such as some of the gamework options before buying.
Either they rushed and screwed the benchmark or there are some fundamental fixes required for the game, really strange behaviour regarding Hairworks that is totally opposite to the situation and issue using it with Witcher 3.
In the FF XV demo when disabled and yet bugged it is very unusual that the characters hair was normal and yet the animals was still enabled, with Witcher 3 it was nigh on impossible to have it that way round as modding Gameworks in that game could only do it for animals and not playing characters that was fixed on when Hairworks is enabled.
If they do fix Hairworks FFXV bugs so disabled is truly disabled and separately still possible disabling Hairworks on character while enabled on animals I will be pretty happy, it was character's hair and when close that really screwed the performance in Witcher 3 with hairworks enabled.
So I will give them some leeway that it is possibly a bug and that in FFXV there are more options around hairworks compared to say Witcher 3; context actual game rather than the FFXV benchmark that has fixed options and bugs that will be fixed for the game (or so Square Enix says but time will tell).
Yeah the demo "benchmark" is meaningless, and if it has these noticable problems how many other mechanics/options are possibly broken in the stripped down test, pretty silly for Square Enix to throw it out there without spending much more time on the benchmark demo and pretty obvious the tech press would identify more obvious anomalies, which is why I feel it is a QA/bugged issue and also does not reflect an accurate assesment of the game due to the various options missing.
Still I would hope no-one pre-orders any games these days, but quite a few general consumers do.
