As mentioned my setup is multiple systems - for these kind of tasks currently E5-1650 V2 with 16GB RAM and RTX3070, 10870H laptop with 32GB RAM and 3070 mobile and 3610QM laptop with 32GB RAM and GTX675M. In the past I've had various other systems in there including 10th and 11th gen Intel CPU based desktops.
For other tasks I've a few other systems i.e. sometimes I run flight radar/ADS-B stuff on a GPD tablet hooked up to a 4K display when I want to monitor a bunch of stuff longer term without interrupting my desktop session(s).
Ah that probably explained why you had lots of system interrupts because you used 16GB RAM and 32GB RAM ran video game modding, coding, texture design, 3D model creation, level design, sound design and a dozen other things on the fly. That not enough memory, 16GB and 32GB RAM are the bottleneck. I found many games developers who are currrent work on Unreal Engine 5 games said they used 128GB RAM ran ran video game modding, coding, texture design, 3D model creation, level design, sound design and a dozen other things on the fly without system interrupts.
I remembered back in 2006, I used Athlon XP 1800+ CPU with 1 core, already maxed 3GB RAM on ASUS A7V333 motherboard since 2001 had problem with youtube playback caused shuttering with CPU hit 100% load. I posted my issue on NVNews forum and people had new CPUs dont had same issue suggested my old CPU was the bottleneck then AMD launched first dual core CPUs in end of 2006 and I decided to upgraded my system to Athlon 64 X2 4400+ CPU, 4GB RAM and ASUS A8N-E motherboard and surprised to see youtube playback ran smoothly no longer shuttering and CPU not hit 100% load.
When GTA IV came out in 2008, I tried to ran the game with 1 month old Geforce 8800 GTX but performance was shocked bad with fps nosedive to less than unplayable 4 fps, I noticed dual core CPU hit 100% load in task manager. I was not really impressed Athlon 64 X2 4400+ was just 2 years old had hit bottleneck. GTA IV was the first game that required quad core CPU as minimum, I upgraded my system to Phenom II X4 940, 8GB RAM and ASUS M3N72-D motherboard then it ran GTA IV much better then later I tried to pushed system further to see how it can handled lots of tasks but CPU hit 100% load with VMWare Workstation.
In 2012 I upgraded system to Intel 3770K CPU with 4 core 8 threads, 16GB RAM and
ASUS P8Z77-
V motherboard, I was able to pushed it with lots of tasks and VMWare Workstation, CPU was sat at about 60% load ran much better than my old quad core Phenom II X4 940 system did.
In 2017 I upgraded system to Intel 8700K CPU with 6 core 12 threads, 32 GB RAM and Gigabyte Z370 Aorus Gaming 7 motherboard, I was able to played game with 500 browsers tabs opened. When Wolfenstein II: The New Colossus came out I was able to ran it at 4K resolution with 16K textures over 60 fps with RTX 2080 8GB VRAM used system shared GPU memory put HBM2 memory to shame. Many people on this forum was attempted to ran the game at 4K resolution with 16K textures with same GPU and CPU but had 16GB RAM saw fps crawled to less than 10 fps. Why? Because 16GB RAM was the bottleneck. The same thing happened with Unreal Engine 5 City Sample demo ran fine on my RTX 3080 10GB at around 40 fps 1080p but other people with same GPU and same CPU but only have 16GB RAM saw fps nosedived to unplayable less than 10 fps.
There are few games like Hogwarts Legacy and The Last of Us Part I required 32GB RAM to run, it wont run well with 16GB RAM. Accorded to gamegpu.com tested these games at maxed graphics settings used 23GB RAM to run 4K resolution on RTX 3070 8GB, 18GB RAM to run all resolutions on RTX 4070 Ti 12GB. 16GB RAM is not enough to run these games while run other tasks.
It will be interesting to see how much RAM memory Ratchet & Clank: Rift Apart will need to run with DirectStorage 1.2 GPU decompression on all GPUs at maxed graphics settings.
I think my next system will need 64GB or 128GB RAM, large Unreal Engine 5 projects like City Sample will need recommended 64GB to run. I was lucky to able to run with 32GB RAM but the memory was hit 95% load. Internet browsers required more memory to run tabs, now 1 tab run Google Search used 425MB compared to 200MB 3 years ago, tried refreshed or reloaded tabs tricks did not helped reset memory hogs.
