As long as the load is "high enough", the clock speed is fixed at the maximum though and you won't get stuttering! "Optimal Performance": very fluctuating frequencies. To show the effects of each energy mode I changed the fps limit while running a stress test. It all depends on the current load of the GPU so if you have a game/program/video or whatever it will cause a certain load and the GPU will try to keep the load "in the middle" and adjust the frequency accordingly. In this mode the graphics card will freely move between the 3 frequency ranges without any borders so you will see clock speeds like 538 MHz or 1746 MHz. These frequency modes are depending on the "load" of the GPU, the default setting mode is "Optimal Performance". 1582 MHz to open end (heavy 3D, "gaming mode") ~700 MHz to ~1100 MHz (heavy 2D applications or easy 3D) 139 MHz to ~300 MHz (idling, youtube etc.) My GTX 1070 has 3 "frequency ranges", which means 3 modes: You will see 3 settings which translate to: When you open your nvidia settings you will find a line called "power management" or similar, depending on your language setting. With the latest generation (10xx) this is a real problem as these cards are overpowered for a lot of games we still play! When I forced it to run in higher frequencies, the stuttering was gone. After a lot of digging I found out that my 970 was running at very low clock speeds. It all started for me with stuttering videos when I moved from a 560 ti to a 970. But they are not flawless!Ī game running in too low frequencies will stutter in most cases! With the modern nvidia cards some really nice energy saving modes got implemented. Pre-words: I will use the word "mode" for the frequency ranges AND for the 3 settings you can select! This is mainly regarding nvidia cards but AMDs have similar things which I can't properly explain due to not having one. I always say "log your GPU load and clock!". You can however very easily find out by monitoring your GPU! If your GPU isn't at full load (90% or higher), it is your CPU! Only case where that's not true is if your GPU is not running in 3D mode! You can not really find out your limiting factor by looking into the CPU. Every now and then I stumble upon people with micro stutter problems or people who need to find out if their GPU or CPU are the limiting factor.Ī great tool to find out is "openhardwaremonitor"!
