Extremely slow performance

[davideb73027874]

I can't explain why it's all so slow; for example in a simple project (one track with one minute videoclip in full hd 60fps) I apply the keylight effect and it can't do the preview in real time (half, third, quarter resoluction it's almost the same)
If I add an audio track, it takes time only to move it back and fort over time.
Moreover, after a while everything seems slowed down, even hitting the space bar to start the playback it takes a few seconds.
It's strange beacuse I have similar problem also with other Adobe programs like Lightroom Classic CC.

I tried to do some benchmark tests and they say everything is ok.

I noticed another thing, while After Effect is working, in the task manager the GPU is almost always 0%-5% and the CPU around 80%. Why After Effect can't use more resources?

it's all updated, I tried to reinstall all adobe softwares and even a clean install of Windows with all drivers and everything.

Any suggestion please?

Hello,

Would you mention the name of the graphic card you have used?

Sorry I forgot to put the hardware specifications:

GPU: msi geforce gtx 1070 armor 8g oc

CPU: Intel Core i7-7700

MOBO: Asus prime h270 pro

RAM: Corsair Vengeance LPX DDR4 2400 C14 2x16GB

DRIVE: Samsung 960 Evo NVMe PCIe M.2 250GB

Hello,

Does your After Effects recognize your graphic card? Would you check GPU information and the cache setting in the preferences?

Preferences > Previews > GPU Information

Preferences > Media & Disk Cache

I think so, these are the screenshots:

I also tried to increase the maximum disk Cache to 40GB but it's the same

You're not using a GPU accelerated effect. Hence, I wouldn't put much into the numbers you've provided for GPU.

On slow performance, clear cache and Memory. When the cache is full, AE slows down a lot - under such a scenario AE not only has to write to the cache but it has to delete old items in the cache.

I would also try different AEPs or Comps with different types of layers - just to see if the issue has anything to do with your Comp Settings+Layer Type+Effects.

And what video format is your source footage?
