The PC market has grown the most. That's a fact. The numbers you site need to be put into context.
The console market has grown but not as much as you would think. Most of the gamers are the same. They buy the new gen console. The PS3/Xbox both sold over 70 million units. The PS4 has already hit that target and the Xbox One has hit about 30 million units.
That's a loss of 40 million units as of now. Meaning (theoretically) 40 million people have moved to PC. Which would also explain it's massive growth. Since we both agree gaming market is growing it would be expected that something has grown, which would be the PC market as it is the fastest growing entertainment market in the world for a reason and it's almost 100% fueled by PC growth. It's a pretty linear trend.
So I disagree with your numbers and to be honest I have never seen those numbers anywhere even from Ubisoft. But PC is the factually the biggest growing market. It's also why more and more games these past few years are coming to PC. We are getting more and more every year for all platforms and that is because the PC market is growing and therefore profitable. So more companies are pushing there IP to PC. So much so they invested into there own stores to compete with Steam.
That's even before we take into account China. Who is a totally different market than anywhere else in the world and they are having absurd growth every year and will if not already be the biggest gaming market in the world. Alongside just being the biggest economy in the world in general but that's a different topic.
Of course, I'm not disputing what you say, PC growth was good. (taken from statista.com) You also need to consider some move from Xbox team to Playstation team and vice versa. The stats I posted were Ubisoft Game sales. What I was referring to is that while we are seeing more come to PC, the efforts behind developers vary from passionate to "lets make it good enough to profit". Many games are ports, and devs are often pushed to outrageous deadlines by publishers like EA, when you don't have resources you can only do so much. Releasing a good playable game, albeit cutdown graphically version that runs at 60fps is better than a poor attempt of multi gpu scaling product, or graphically enhanced IP (Batman Arkham knight)
Square Enix on the other hand have worked hard to release same titles on PC with considerable delays, and they paid off because FF15 Looked fantastic. GTAV delayed heavily but also produced one of the highest selling games on pc.
But look back at Ubisoft and even Bethesda products. Crew2 (crew 1 also I believe) capped at 60, entire game is a port from console with a horrible menu system, and the method to quit the game was thrown in afterwards. Shocking to see "how do i quit Crew 2 on PC" such a popular google search.
Division was heavily cut down from its unveiling, has unlocked fps but 5% scaling on multigpu. Watchdogs, same thing. Bethesday games Skyrim and AC series cannot handle 120fps because entire game turns into a pinball machine.
I love the fact that PC community is growing but I just don't know if its enough right now for developers to turn their attention more to utilise what we have in our cases. After all, we all have different components in our case and they need to make them all work smooth.
hmm maybe I should have made a separate thread.
tl;dr I like seeing more console games come to PC, but I have given up on the FPS lock battle.
