Hey everyone,

I’m having a really frustrating issue with League of Legends performance and I honestly don’t know what else to try.

I’m running the game on an RTX 5070, so hardware shouldn’t be the problem at all. I’ve capped the game at 80 FPS to keep things stable and avoid unnecessary spikes.

At first, I noticed that playing in Fullscreen caused random drops down to \~50 FPS, which made no sense. So I switched to Windowed mode, and yeah, it mostly stabilized… but not really.

Now the issue is that during teamfights or even some trades, I get sudden stutters where FPS drops from 80 to around 55–50. It feels super inconsistent and throws off gameplay completely.

What’s weird is:

• It happens even on LOW settings
• Temps and usage seem normal
• I already tried basic optimizations (drivers, settings, etc.)

At this point I feel like I’ve tried everything and the game just refuses to run smoothly.

Has anyone experienced something similar or knows what else I can tweak? I’m open to any suggestions because this is driving me crazy.

Thanks in advance 🙏
