The framerate. I had always played on console. Loved it. Went to a friends house and they were all like, "hey want to play some games?". So he sat me down at his computer and I had no idea what I was doing with a K&M. Once I saw the smoothness, I was in love. Then I started a new game, building my PC which got me even further addicted to PC gaming. My first gaming PC was an GTX 760/I5-4440. Since then, I've moved to a GTX 970 > 1070 > 1080 > and now a RTX 2080Super/9900K. Unfortunately, the "upgrade game" is a game I'll never beat...
I got into PC gaming as a kid when my mom showed me her DND Goldbox games on DOS. I remember being so excited first for Baldur's Gate and then for Neverwinter Nights. I branched out to other titles like Age of Empires and Civilization, and I've been playing PC games (not to mention DND) ever since!
Classic Sierra adventure games got me hooked on PC Gaming in a big way. The Quest for Glory series being my favorite games of all time. I also fondly remember the Cinemaware games. Also I loved the SSI AD&D games, especially Dark Sun: Shattered Lands and Dark Sun: Wake of the Ravager. The Ravenloft SSI games were really fun too.

Realizing that mods were a thing for fallout 3, then proceeding to cleanse the capital wasteland of mutant scum using a bolter and chainsword from Warhammer 40k was definitely what got me hooked on PC gaming!
What made me a PC Gamer and what ultimately got me hooked was in the mid 90's there used to be actual brick and mortar stores. It was a total experience walking into actual dedicated computer gaming stores. PC games came in the big boxes. Often they would come with huge manuals. I started out playing games like Janes Fighters Anthology. I used a Microsoft Sidewinder Force Feedback pro. It was an amazing time for PC gaming. I played games like Novalogics Delta Force 1 and 2. There was a game called 7th Legion that was pretty cool for the time. I played Falcon 4.0. There were games like the first Unreal Tournament which I played heavily. I ended up buying a computer with the first 1ghz processor, it had the Amd Athlon Thunderbird processor.
I ended up being a PC gamer almost "by accident" when I was gifted a hand-me-down PC years upon years ago, and the convenience of an open platform and multiple input choices when it comes to games is a big deal of why I stayed a PC gamer.
I got hooked on PC gaming by sitting next to my dad as he played through wizardry vii. I remember when he was done that I'd try for hours to make the perfect party. It was a real pain in the butt in wizardry, because even certain classes couldn't be unlocked without having lucky rolls. I also remember him never being able to finish the game because of a gamebreaking bug near the end.
Learning basic commands and the file structure on a Commodore 64 got me hooked way back in high school. It didn't help that some railroad simulator had taken my attention from my console gaming! From there, it was on to Team Fortress and Quake 3.
