Yes, I completely agree, BrainWarp is not very convincing, there are nuances.
I noticed this on the very first day when I tried my 8K in Assetto Corsa. The picture was not smooth. Then I turned off BrainWarp and set up the game for 80 native FPS, everything became very smooth.
After that, I do not turn on BrainWarp (“smart anti-aliasing”) at all. Better to reduce supersampling than turn on BrainWarp. He only makes the picture worse.
I mentioned this in my review:
At first, when I turned on the first game (AssettoCorsa), I didn’t really like the picture in the helmet. One thing is that there was a small SDE on the horizon (but it was a little easier to forget about it than in Lenovo Explorer, the difference between them is really small in terms of SDE. Lenovo has a specific pixel pattern in the form of bricks, which sometimes torments my eyes. But 8K has quite a normal diagonal pattern, which is less noticeable, this is a plus for me).
It’s another thing that I didn’t have any smoothness. I compared it to Lenovo Explorer, everything was very smooth at 90Hz, the feeling of speed was felt right there. And it was like there were missing frames here. Then I realized that smart smoothing worked (or BrainWarp differently). I looked to the side when driving slowly on the track, and noticed that all the objects slightly double. But that’s how BrainWarp works, so there’s nothing you can do about it (although in other games it’s a good way to help, but not in games where speed is important).
When I turned off BrainWarp and tuned in the native 80 FPS, I finally felt the smoothness and sense of speed. At the same time the picture became much more pleasant, there were less stairs and jags, the game just changed. And what is the most important thing - it became obvious that SDE is really lower by 8K than Lenovo Explorer. (but initially it was difficult to understand the difference between them because of the poor quality of the picture, lack of smoothness.)
