A known issue with AMD processors and graphics cards is causing FPS drops in League of Legends. Here, you will learn how to fix the FPS drop issue.

Released in 2009, League of Legends is still one of the best MOBAs in the world and wins the best Esports title almost every other year. Riot constantly pushes new updates, skins, champions, and reworks to make the game interesting for the players.

But, being such an old game, League of Legends does have a fair share of issues — especially having spaghetti code that brings a lot of limitations. It’s already a meme among the community, and even many Rioters openly discuss how those limitations prevent them from making advanced stuff.

However, going back to the topic, a Reddit user posted on Patch 12.12 bug megathread that having Ryzen processors & graphics cards causes FPS drop & lag in League of Legends that usually occurs after 5-8 minutes. After that, other AMD users also shared their bad experiences and asked Riot to address the issue immediately.

How to Fix the FPS Drop Issue on AMD Processors & Graphics Cards

Though there is still no official fix from Riot Games, Reddit user u/UndeadMerv, came up with a temporary solution that will solve the League of Legends FPS Drop issue on AMD Processors and graphics Cards.

According to u/UndeadMerv, disabling SMT (Simultaneous Multithreading) from BIOS or AMD Ryzen Master software stops the lag spikes and FPS drops.

If you don’t know how to disable the SMT from the BIOS, follow these steps:

  1. Reboot your PC
  2. Press the “F2” or “DEL” key to enter the BIOS
  3. Go to “Advanced Settings”
  4. Go to “CPU Configuration”
  5. Disable SMT from “SMT Control”

The steps may vary slightly from processor & motherboard to motherboard. For my case, I have a Ryzan 3700X processor, and I’ve found that: BIOS > Overclocking > Advanced CPU Configuration > SMT Control.

It is a temporary solution, and some may face other general work-related issues after turning off SMT from BIOS, as SMT’s main job is to improve the CPU’s overall efficiency.

Moreover, ensure your PC meets the minimum specs to run League of Legends, as Riot updated the minimum and recommended specs requirements last year.

When will Riot fix the issue?

Though there is no official announcement from Riot Games, replying to a support ticket, Riot did acknowledge the issue.

“This is actually a known issue with AMD processors and graphics cards that we are investigating,” Riot said. “We don’t have any ETAs on a fix for this as of now, but hopefully, we can see one in a patch/update in the near future.”

Sadly, there’s no release date as of yet. However, as it’s getting a lot of attention from Reddit, we can expect Riot to release the fix very soon.
