Does GZDoom or ZDoom lag for you guys using megawads?

So I am curious is anyone has any problems running megawads on GZdoom or ZDoom with actors over 10,000?

Can GZdoom even handle this many actors or is my system to blame? I've tried it on both an Apple M1 laptop and my current windows rig:
Ryzen 1600
2x8 16GB Corsair 2666 mhz (OC to 3000)
EVGA GTX 1060 SC 3GB
ASRock AB350M Pro4
512GB SSD
EVGA 650W PSU
Windows 10 w/latest update

It seems to run fine on Zandronum with no lag but GZdoom (tried lots of old and new versions) ZDoom or any of these sorts just lag bad.
Software and hardware modes both take a hit of 30-40 FPS with 10,000 actors moving at once and then tested like 9000? actors on screen in front of me it tanks to 1-2 FPS!

I like having fun with the console commands like fire rate and infighting 1 plus it can play Brutal Doom which also lags when lots of gibs are on the screen.

Tried swapping parts too with my friends PC, swapped to a B450 motherboard, new RAM brand with faster 3200mhz, swapped SSD brands plus size, used a Ryzen 5 3600 which was the only thing that increased FPS from 1-2 to 3-4. Don't think the GPU is the factor since usage gets lower after 5000 actors (CPU bottleneck?) even then i assume i won't get 20-30 FPS extra with a new GPU.

Have you guys manage to run megawads at 60FPS+ above 6000+ actors? That's where my computers starts to weaken. Kinda feels like GZDoom wasn't made to handle this many actors like Zandrodum or original Doom does.

Thanks for reading.
