Disgruntled Borderlands 3 players on PC are unhappy about the numerous connectivity and performance problems they’ve encountered barely a day into the game’s launch, and they’re letting people know about it in the forums. For Borderlands 2. On Steam.

You’ll recall that Borderlands 3 is an Epic Games Store exclusive. Epic Games Store does not have forums. Nor does it have user reviews, thwarting the primary means of revenge for disappointed PC gamers. For while players are lighting up the franchise subreddit, the PC gaming subreddit, and the official forums at Gearbox Software, nothing says spite like unloading on a seven-year-old game in a marketplace that can’t even sell its sequel.

One Steam user pleaded with Borderlands 2 fans not to engage threads on Borderlands 3, and included a link to the Gearbox forums. People are still popping in questions and requests for help with Borderlands 3’s performance. Framerate drops and stutters appear to be the biggest bugaboo facing PC users.

“Need help,” wrote one player, “regardless of the graphics settings, frequent reductions in FPS, CPU and GPU are only loaded at 60%, RAM at 70, but the hard drive jumps from 0 to 100% and hangs at 100% when FPS reduced. I already turned off all Windows services that might be the reason, I also checked the disks, fragmented them, can there be a reason that the game is installed on the same disk as windows?”

“Try an actual Borderlands 3 forum,” someone replied. “You’ll probably get more responses.”

“ty,” OP replied.

The most recent guidance from Gearbox Software’s official Twitter account is that the studio is investigating all of these various issues, and users are being steered to 2K Games’ official support site to log a ticket.

Back in April, when Gearbox announced Borderlands 3 — and announced it would be exclusive to the Epic Games Store — angry PC gamers flooded the user reviews for Borderlands 2 with enough negative remarks that it triggered Steam’s first ever “off-topic review activity” flag, set up to combat “review bombs.”

Borderlands 3 launched for Windows PC, as well as PlayStation 4 and Xbox One yesterday. Our review noted that the version we played was “obviously not … a finished version” that featured frequent crashes for users on three different gaming PCs.
