Why I have low fps?

My pc specs: i5-9600K, RTX 2070 SUPER, 16 GB(8x2GB) RAM 3200Mhz, 2 TB HDD, 256GB SSD.

In all games that I play, I have low fps. Example: In The witcher 3: Wild hunt i have 75 fps and rare fps drops to 50 fps, on ultra settings, but on YouTube, all have 100-120 fps on ultra setting(I mean with my specs).

@dannyability: Wrong board. Let me move this to the correct forum: PC/Mac/Linux Society

@dannyability: What resolution are you running at? Also, if you have hairworks on, it will have a large impact on performance.

@BassMan: At 1080p, and i don’t know if hairworks is on, but it’s in the witcher, what about Hitman 2 with 75 fps and fps drops to 55?

Hairworks is a setting in the game. Make sure to turn it off to increase FPS.

@BassMan: Thanks, but what about hitman 2, in the options I dont see a hairworks option(sorry for bad english)

Hitman 2 does not use hairworks. I have not played the game, but you can always check what may be causing performance issues with MSI Afterburner. See if there is a bottleneck with your CPU or some other issue. Your GPU should be showing full usage as long as you have Vsync off and have not set a frame rate limit. If you are not getting full usage on the GPU, then there is some kind of bottleneck, an optimization issue with the game, or an issue with your GPU drivers which may be fixed by uninstalling them with DDU (Display Driver Uninstaller) and then re-installing them.

@BassMan: Man, you are genius, I turned off Vsync an I have 150 fps in The witcher 3, man thank you!!

@BassMan: but what is Vsync?

@dannyability: Vsync sets the frame rate to the refresh rate of your monitor and prevents screen tearing and the GPU rendering unnecessary frames. It works best when you can keep a steady frame rate the same as your monitor's refresh rate. I recommend using Adaptive Vsync in your Nvidia Control Panel. This setting will disable Vsync when the frame rate drops below your monitor's refresh rate and will prevent stuttering.

@BassMan: thank you

You're welcome.
