Doom 64 Dreamcast by

[@TheFieryWind99]

An Immorpher video running at 60 FPS would be unbelievable to me many times ago. Either way, it's nice seeing the Dreamcast port still get updated!

[@Immorpher]

Haha, ya I normally dont set my capture to 60, but now its kinda mandatory for these updates!

[@mankrip-]

This engine is begging for someone to make an original Dreamcast game using it. Best Dreamcast homebrew I've seen so far. Only needs splitscreen co-op.

@jnmartin84 Unfortunately, I know nothing about Doom engine architecture.

This looks really nice at 60fps, may have to break out the Dreamcast, what resolution is it running at?

[@jnmartin84]

640×480

Does texture filtering impact the framerate?

[@Immorpher]

We aren't quite sure! I personally haven't seen a very consistent change in frame rate. But perhaps if I did some over time averaging, it might show itself! I will ask around too!

[@jnmartin84]

@@mankrip- My understanding is that twiddled/swizzled textures make filtering basically free on the pvr

[@jnmartin84]

I haven't noticed much of a difference on or off. Something that does kill performance is when a textured quad with holes takes up most of the screen and every pixel behind it has to be tested for blending. Makes 60 fps scenes drop to 30

[@jnmartin84]

@@mankrip- turns out it can have a large impact on fill rate/frame rate. I noticed before when grates were stretched over large polys covering screen the fps halved. I just observed that this does not happen when running with filtering off

Holy fuck, THAT'S SMOOTH AS FUUUUUCK! Also, Forte 6.6.6. here. Subscribing to you cuz I forgor to do it.

[@Immorpher]
