And clients are using Windows. Microsoft are not some idiots, and they are #1 player on the market (just like Adobe, Autodesk, SAP). When dealing with this kind of a fish, it is YOU who has to comply and listen to, whether you like it or not, to be able to survive. Now the reality is that for the next 10+ years MS will be in force, and you have to comply. Graphics Card Drivers of NVIDIA are working (and has been) from the very beginning of this W11 story, and they are more complicated (sophisticated) than any UT2004-engine-based game. This is just the proof that from the inside W11=W10, and that the difference (at least by now) is only in the outlook, and, given that the game was working fine BEFORE the Wed. 07.28 maintenance, makes me believe that tech. support's answers (in this regard) are just regular plausible deniability from their side, since their NCWest coder guys were already making thing (old GameGuard) which is working for both W10/W11.
I am pretty sure, that this kind of ppl (programmers/developers) are among the first who are actually joining Windows Insider Programmes and having this alpha Windows' builds at their homes. Just because of the curiosity.
Also, wanted to elaborate on some silly suggestions. To disable Windows Defender. You said what?
What kind of a company can make this kind of suggestion? To shutdown the protection? You are not some random company from the street convenience store selling drugs to kids. You are serious company, who, among other things, are taking player's money and has the financial account. Representatives of the company can't suggest malicious things which can put the user under financial/physical risk. Should this be to jump off the cliff or to disable windows defender.
And, if I'm robbed by fishing my credentials later on? Who is responsible?
Pretty sure that nothing is said in the EULA about "disable windows defender or any other anti virus software to play the game". You are not on some beta stage to declare that the popular anti-virus software may not be compatible. It is not client's job to "make sure that the game is operating within an anti-virus environment". The big fish on the anti-viral market are: Microsoft, McAffee, BitDefender, Norton, Kaspersky (afaik sanctioned in the USA). It is the software developer's job to either make your software compatible, or, (as I imagine this scenario in my head) to negotiate directly your software with an anti-virus developers to "make" it compatible.
