Has anyone else experienced very low FPS 20-40 when not that long ago having 100+? I can't recall which updated of Ubuntu or Dota could have caused it but my potato PC is not a toaster (I think) (Intel® Core™ i7-2600 CPU @ 3.40GHz × 8, GeForce GTX 950/PCIe/SSE2, 6GB RAM, SSD). Got 375 Nvidia driver installed, tried others, same result. Maybe there's someone that knows what could it be?
