I'm honestly curious if this is truly the case. I remember reading an interesting research article a while back (written by a woman) about how the early versions of the Oculus Rift gave women headaches at much higher frequency than men.

The basic conclusion is that, on average, men and women's brains often use different cues to interpret depth and motion, which resulted in women getting headaches from the Oculus Rift at higher frequency.

Sure enough, military researchers had noticed that women seemed to get sick at higher rates in simulators than men. While they seemed to be able to eventually adjust to the simulator, they would then get sick again when switching back into reality.

Scholars in the gender clinic were doing fascinating research on tasks like spatial rotation skills. They found that people taking androgens (a steroid hormone similar to testosterone) improved at tasks that required them to rotate Tetris-like shapes in their mind to determine if one shape was simply a rotation of another shape. Meanwhile, male-to-female transsexuals saw a decline in performance during their hormone replacement therapy. Along the way, I also learned that there are more sex hormones on the retina than in anywhere else in the body except for the gonads. Studies on macular degeneration showed that hormone levels mattered for the retina. But why? And why would people undergoing hormonal transitions struggle with basic depth-based tasks?

What I found was startling (pdf). Although there was variability across the board, biological men were significantly more likely to prioritize motion parallax. Biological women relied more heavily on shape-from-shading. In other words, men are more likely to use the cues that 3D virtual reality systems relied on.

It's purely conjecture, but ever since reading this article I've been curious if there is a biological male advantage in certain types of gaming. This is not intelligence- the article is talking about perceiving motion from 3D-rendered images on a screen. Not one that's necessarily insurmountable or even uniform- maybe it's something that disappears when the brain gets used to it - or maybe it doesn't exist at all, and it stems from the fact that men tend to be encouraged to play videogames as children and women don't. It's incredibly hard to know, because stereotype bias is a problem. We do see outlier female top players (SuperGirlKels in Smash 4, Gegury in Overwatch, etc).

Note: I tend to lean towards the "women tend to be seen in lower numbers in tournament bracket because of social pressure, not innate reasons" camp, but I found the article interesting and made me consider that we simply don't know. It (the article) may be completely inapplicable because it has to do with 3d images like the Occulus Rift, but even the author herself (who is a programmer) applied it to women playing video games in one of the opening paragraphs (purely conjecturing, however).
