We (Riot Devs) are aware that some Players are experiencing a bug where the frame rate of League or TFT drops suddenly somewhere between the 5 to 10 minute mark and stays low or erratic for about 5 minutes or so. We have been unable to reproduce this issue internally, so we’re reaching out to you, the players, directly to try and identify the cause of this issue.
If you are experiencing these symptoms, please respond with details in the following format;
- GPU driver version:
- Reproduction rate: (eg every game or once every 10 games)
Optionally (you don’t have to do these, but this information may help)
- What overlays are you running (Blitz etc)?
- Did running the game in DX9 mode help? (You can do this via settings/Game/Prefer DX9 Legacy Mode)
- Did running with SMT/Hyperthreading turned off help? Y/N
Additionally, if you can send me the .rpd file found in "League of Legends/Logs/Performance Logs/" just after you've played a game in which you experienced this slow down, that would be awesome. (The rpd file stores per frame performance information for the last game played. It will really help diagnose this problem).
Thanks in advance for your help with this. Hopefully we can finally get to the cause of this and provide a fix for you all.
[Edit] Let me just emphasize how useful RPD files are for identifying this issue. If you can, please, give me your RPDs!
[Edit2] I'm looking for information on JUST the case where there is a consistent degradation of performance after about 5 min into game, and for a few minutes after that. Not any and all random FPS drops.External link →
