Drop frames & performance issues

Hi,

I've been dealing with some drop frames issues using MexedCam_Unreal_Preview_3+3-Cam compound.

When I change between VCAMs and TCAMs it starts performance issues and drop frames, not at all time.

Aximmetry Broadcast DE Edition 2021.3.2 build 20596.

Here are the computer specs:

11th Gen Intel (R) Core i9-11900KF@ 3.50Ghz
RAM 64.GB
NVIDIA GeForce RTX3080 ti graphics card - driver nvidia 472.84
64-bit operating system

c:\ - nvme 2TB
d:\ - HDD 4TB

(VCAM) GPU: 59% - CPU: 84% - FPS: 60 - vMem: 5%

(TCAM) GPU: 46% - CPU: 49% - FPS: 60 - vMem: 6%

I used GPU-Z, temperature seens ok. GPU Temp: 58.1 max, CPU Temp: 62 max CelsiusAllow Virtual OFF
I tried almost everything and have no idea why it happens.

Hello Iveiga,

Without taking a look at your project/scene it’s hard to know what might be causing the performance issue. From our experience, it is mostly caused by unoptimized Unreal scenes. There is plenty of optimization tricks and tips that you may find online on Unreal forums and Youtube Tutorials.

I agree with Ahmed@Aximmetry, I have a 5 cameras/5 billboards + 8 videos screens and Sequencer animations and I run at 30% in GPU and 35 % in CPU (RTX 3080). My Unreal scene had been optimized a lot to gain fps. Mainly by baking all lights, merging meshes, simplifying materials, avoiding too much cast shadows, and so on...
