My video

Because of my low GPU usage ，my FPS is even lower than 1070ti in some games ：（ （ultra setting 1080P）

My power supply is 550 watts. The temperature of video card and CPU in the game is about 70 degrees.Using the latest Nvidia driver.The BIOS version hasn't changed since i bought the motherboard last year.My own inference is that my ram frequency is not high enough，maybe I should try to buy two 4000MHz ram?

I just used that video to show that 8700k shouldn't be a bottleneck. I've seen a lot benchmarks of GTAV and Battlefield 1（also using 1080ti 8700k 2X8GB，even memory frequencies are lower than mine.），the biggest difference is that their graphics card usage is stable at about 90 percent，and mine is mostly around 80 percent, sometimes even down to 60 percent. I watched a lot of popular science videos on hardware.，youtubers usually emphasize that CPU and GPU need to be matched properly，but in fact, 8700K after overclocking shouldn't be the bottleneck.And I also use dual-channel memory. Besides, I do have some problems with game crashes. After I overclocked the CPU and memory（8700k 5.0ghz 2x8GB 3200MHZ）, I used AIDA64 for half an hour of stability testing. But when I play games（I only played BF1 and BFV these days）, crashes often occur after 20 minutes gaming.And another extremely annoying problem for me is that whenever there is an explosion in the game, my GPU usage drops to zero in an instant.

6700k and near 99% GPU usage...This means that at least my 8700K in GTA5 is not a bottleneck.

But what really bothers me is that in many benchmarks, other people use the same configuration as me but have higher GPU utilization and fps.I really can't figure out where my configuration bottleneck is.

144hz Vsync off

I don't think that's the point.Many game benchmarks use the same configuration as I do and run at 1080P resolution, but their GPU usage is very high.

I saw some benchemarks， their GPU run 96~99% in the same game

1080p. I know 99% is full utilisation，but in many other games my GPU usage only 65%~85% (gta5 farcry5)

nope.My GPU usage is 99% in Rainbow 6，but in some open world games, CSGO and battlefield 1 the GPU usage is very unstable（Floating from 99% to 70%）.I was very puzzled to find that my CPU was not full at this time，and don't know where the bottleneck is.

PLZ help me！ In many games, my CPU and GPU usage both very low，（GTA5 SQUAD COD:WW2 RUST Farcry5）Using 8700K (OC TO 5.0GHZ) 1080TI 2X8GB 3000mhz .I use monitoring software to monitor the usage of each CPU core while playing games, and none of them is full-loaded. There is no CPU bottleneck in common sense，but GPU usage is still very low.I want to know what went wrong. To solve this problem, I spent the whole night trying CPU and memory overclocking, but it didn't work. It really bothered me.
