"Absolute wrong advice!" "Anisotropic filtering in 1946 has almost no impact on FPS at all" if you have a powerful computer you will not notice, but when I had slower computers
I clearly noticed the FPS crash, that's obvious!
Whatever you think you have noticed, it wasn't the impact of anisotropic filtering for sure.
Remember your advice was not just to disable AF, but also to massively
increase AA and what I've said - and what remains true - is that AA is the FPS hog, not AF.
If you want to make people believe that on "slower computers" your AF statement was true, take note that the AF impact depends on the game engine and the graphics card being used.
The last Flightsim game with crappy AF implementation I can remember was Lock On - the original one I mean - that was 2003.
Geforce 4 graphics cards back then suffered a performance hit of up to 20% with 8xAF enabled (16xAF was out of reach to Geforce 4 cards).
ATI cards didn't suffer such impact at all, even the good old Radeon 9000 Series.
Nvidia partly fixed it with the Geforce FX series and completely fixed it with the Geforce 6 (like 6600GT) - that was 2004.
IL-2 1946 and any other Combat Flight Simulation game have a perfectly fine AF implementation. The impact of enabling 16xAF on a Geforce 6 series GPU is less than 2%.
What you've told was and remains wrong.
Deal with it.
Cheers!
