@heavy crater IL2CPP Build performance
BIRP
Day light 300 fps
Night light 280 fps

HDRP
Day light 265 fps
Night light 250 fps

Hmm, interesting, I wonder why is not consistent

#

It dropped performance on day light but was enhanced on Night light

weary hedge
#

there were more serious differences when I tested it in earlier versions. Especially HDRP performance difference between editor and build has decreased.

got it

#

so a high increase of batches is expected

#

it went from 1873 to 3317, that is an increase of 53%

#

ain increase of 15% in shadow casters

#

increase of 48% in setPass calls

weary hedge
#

you probably don't have Depth Normal prepass in your project. This is the reason for the increase in the number of triangles. The shadow caster is probably different because I can't fully adjust the cascade settings.

oh thanks

#

will run it here but I expect is going to be the same

#

I appreciate this, this is good to have something to measure against

weary hedge
#

Use Win + G for FPS. I did not add any counters.

#

sounds good

Pros of HDRP
volumetric fog
High quality Decal (better than unreal engine 5 decal)
shader graph
VFX graph
Physical based lighting (hard to adjust but looks more realistic)
PCSS
better forward and deferred light performance.
better quality Post process effects.
ray tracing
DLSS, TAAU, FSR, upscale...
Optimization with distance light, shadow fade options.
being able to choose which features the camera and reflection probe will use.

@heavy craterI'm so sorry, there is a mistake in the values. I accidentally forgot Forward the night camera. I updated the FPS values.

heavy crater
#

oh thanks, that makes more sense

#

The Pros are very attractive, not sure if the performance cost is right

#

I will have to do a research on what would be the user's preference, would they rather have better graphics or they prefer the game to be easy on their computers

#

Right now we got graphics into a state that some might think it looks like UE4 and it runs very well on most computers

#

We are now considering doing the next gen jump in graphics but are concerned about the impact on customers

@weary hedge thanks for your time to actually take time to test the differences between the two. What do you think about adding URP to the comparison? Or maybe if you don't mind, a link to the test project would be very much appreciated.
Once again, big thanks
