I discovered something surprizing. Low CPU and GPU usage during frame rate drops.

I have made a thread a few days earlier stating that my frame rate most of the time is around 50 FPS, and that at some parts it falls to single digit numbers, and that changes in the graphics quality of the game has absolutely no effect.

I decided to test the game to see CPU and GPU performance, and I've discovered something surprizing: At no point the game used either 100%, and when the frame drops occur, both the usage of CPU and GPU drops instead of increasing! That means that neither is responsible for the low frame rate, and that they wait for the game to do its thing and send them more commands to execute.

While not at a framedrop infested zone, my CPU is used about 63% max, and my GPU about 74%

When a framedrop occurs, CPU usage drops down to 20s and 30s percent, and GPU usage between 0% and 44%.

The more severe the frame drop, the lower the component's usage falls.

That practically means that neither my CPU or GPU are causing a bottleneck, and well my RAM is 8gb, so that shouldn't be either.

That leads to the conclusion that there is a software bottleneck, ie horrible engine optimization.

Here are screen captures of my tests:

Interesting. What about HDD use?

[Alithinos]

The HDD that the game is installed at is between 99% and 100% all the time.

A usb drive I have with Windows 'readyboost' feature flanctuates between 0% and 100%.

its definitely a software bottleneck, im still hoping for a “TESV Acceleration Layer” type fix.

Huh weard this has happened to me as well I have a gtx 980 overclocked to 1500 MHz and overclocked the stock clock by a bit over 200MHz and an amd fx 8320 overclocked to 4.8GHz my cpu load for the 1st core never goes above 60 the others stay around 30-40 and my GPU stays in the 20-60 range. Oddly on vats and in menues the GPU ussage goes up but in big cities it stays low.Have 8GB of DDR3 16000 RAM. With windowz 10. Use MSI Afterburner to check this out. Also seems to happen with others games as well.
