Frames. Per. Second. Total advantage over anything. I'm sorry, we $HIT all over console players on Rocket League because not only is our image more clear and crisp but our FPS never dips below 150. I own Rocket League on both PS4 and PC and the PC experience is so much better in every way. Somebody explodes on PS4? Enjoy your frame drop and lag. Somebody explodes on PC? It doesn't give a ****. Want to take that smoke away so you have an advantage? Just modify INI. Rocket League works well because it's particularly hard to have an extreme advantage over everybody in just skill. It takes teamwork and a lot of other factors are in place. When you party up all PC and you're good players against PS4 it's a slaughter fest. Idk how many times we've made people rage quit due to score.
The same can be said for shooters. Higher the FPS, lower the ping, the bigger the advantage. Of course if you're a **** player it won't help, but I'm speaking generally if you're a good player it'll give you more of an advantage. This is largely why cross platform gaming hasn't been a thing. There were studies and PC people just **** all over console people. I'm glad they want to reopen the possibility but I doubt it'll go very far past Rocket League.
Other examples of PC advantage. LoD, draw distance, FoV, precision, no aim assist, FPS, resolution, Anti-Aliasing, INI modding, ping*, shadows off, loading time, withhold updates, and last but not least troubleshooting. If you have a problem with a game on console you're ****ed. Wait for an update or pray to your friend's mom's boobs somebody has an answer on Google that works. On PC it's usually something stupid that can be fixed with ease.
*ping: I've never seen ping as low on PS4 as I have on PC. Lowest ping on ethernet has been 28, lowest on PC 4.
