Question GPU bottleneck or failing?

My son peaked my interest in creating environments in Unreal Engine 5.

As I progress through creating my level, the more grass and trees I add, the harder it gets to keep a decent fps, which is completely expected. However I thought I had the hardware to support the stress.

Even more so, if I am in the program for more than 10-15 minutes, the rendering (I hope that is what this issue is called) seems to drop and instead of a tree or a house, it looks like a untextured blob of garbage.

Not all my assets are untextured like this, just specific things such as any 3d models homes or single assest of groups of trees. I check the cpu usage in my Adrenaline app and its usually fairly low at 15% with the occasional spike up to 40%.

The GPU is usually 99-100% with temps in the 50-60 degrees, and hotspot temps in the low 90's. Fan rpm usually stay at 1700. I see other people with lesser hardware on youtube not experiencing the same issue I have.

The wattage of my GPU is only drawing 160-170. Im not a heavy gamer or anything that requires a crazy cpu.

I did get a decent deal on a black friday 5800x so that is on its way, but I feel that my GPU should be performing better than what it is. I read up on the power draw and it seems that others say this is normal to be this low.

The Trees look like sparkling 32 bit graphics. Gets slower as my C drive fills up with Unreal data even though I have my installation on another drive. I cant seem to remedy this issue.

Current specs as follows

Ryzen 5 5600
Asus B550M
32g Tforce Ram @ 3000
Sapphire Radeon RX6700XT 12g
New Aresgame 1300w PSU.

Hey there,

Whilst I haven't created environments with UE5, I've mostly just toyed around with the demos. It runs like a turkey, as in, all over the shop - at least with FPS. I've quite a similar system to yours, with maybe slightly stronger GPU and I really don't see FPS above 50. If the max FPS is 50 you can be sure the 1% lows are much less, and this creates a stuttery mess.

New CPU might get you a few more fps, and better lows too. Good gaming CPU. Ram would be slightly holding you back a few fps too. Some 3600mhz CL16 would be great, as you could also get your ram running synchronously in a 1:1:1 ration for the mem clock/infinity fabric clock/mem controller clock, which is great for latency. Your system would feel a little snappier.

How full are your SSDs? You need a bit of space on ssd so that they don't slow down to much.

Are all system drivers, including chipset and GPU up to date? What bios are you running on the mobo? Ideally it should be somewhere up about 3607. If not consider updating this too.
