Why is my viewport frame rate so slow? My pc has a
CPU- Ryzen 9 3950X
GPU- Quadro RTX 5000
RAM- 124 GB of G.skill Trident
Motherboard- Giggabite Aorus x57
SSD- Samsung 970 Nvme M.2 1TB
in it. But, when I use the &quot;Grassgwald&quot; add-on, the frame rates in my viewport drop so much, I cannot rotate my model. There is a huge delay. There is a lot of grass in the seen, it is on a large plane depicting about 100x250 square Feet.
I have installed all drivers for my GPU and they are up to date. I have also made sure Blender recognizes the card. Since it is a Quadro RTX card, I have the option to use Optx as well as Qudo Cores in the options menu. I have tried both, neither changes performance.
To be clear, this happens when I am in the &quot;shaded&quot; tab with default settings. It also happens when I am in the &quot;layout&quot; tab with default settings.
I was lead to believe this GPU could handle this kind of load. Does ANYONE have a solution, or is it unrealistic to expect that much from my set up? please help. Thank you

One of the problems with blender right now when using particles system is that it is not easy (or nearly impossible) to make the instances avoid each other and not overlap, and thus cover maximum space.
You Setup is great, I'm thinking that you have too much grass in your scene, probably more than you need to cover the surface. If you show me a screenshot of your scene or your particles settings at least, I can pinpoint (and I will update this answer accordingly).
PS: Also, just a friendly tip, yes Graswald is a good add-on, but do consider checking out Scatter add-on
