Lag after upgrading PC

[stanzlavos]

Hi All

I recently upgraded my desktop (no change in GPU). Configuration :

AMD Ryzen 9 5950x

32GB (2x16GB) 3600Mhz CL16 RAM

GTX 1080

Windows 10

Note : I have been using "GPU accelaration" previously (Intel 5820K + 32GB (4x8GB) 2666Mhz CL15 RAM).

Issue :

• If I disable GPU accelaration, 
  • dragging around a zoomed in image is kinda smooth
  • the mouse pointer movement is kinda smooth
  • when changing a global setting like "clarity", the image on the screen becomes blurry and updates if I move the mouse! (or after a few seconds)
• If I enable GPU accelaration,
  • dragging around a zoomed in image is horrendous!
  • the mouse pointer itself  "skips frames" periodically
  • when changing a global setting like "clarity", changes are updated almost immediately.

I also read an article that said that there were some issue with Lightroom on a 5950x!!!

Any suggestions ?

Thank you. 🙂

Is this a homebuilt or prebuilt rig?

[stanzlavos]

Home built. 🙂

Motherboard make/model?

And what cards in what slots?

ah, my bad, you stated "I just have the GPU and a PCIe Gen 4 SSD" so, thst PCIe SSD uses a slot?

Asus ROG Crosshair VIII Dark Hero

Ryzen 9 5950x

GTX 1080

The NVME PCIe Gen4 SSD occuppies the M.2 slot that connects directly to the CPU. 🙂

I have a similar system using a much lower performance Intel 8700K with no issues. I doubt it's due to the AMD 5950x CPU.

I am using the catalogue file from my earlier installation. Could this cause some issues ?

[Todd Shaner]

It shouldn't cause these issues, but try creating a new catalog and import a few of the same image files into it. See if it performs any differently.

Will try this out. Thank you. 🙂
