Particles appear as right-angled triangles if rendered at a distance. #194

With my PC on the GTX 1080, it always renders the distant particles as triangles no matter the video settings I use.

(On a side note specifically for integrated Intel graphics 615: anisotropic filtering actually forces linear texture filtering on everything preventing the ability to have nearest neighbour + anisotropic on at the same time. Even the menu/HUD/console incorrectly has linear filtering applied to it. Intel graphics isn't so hot with Vulkan.)

Win10 w. latest drivers etc.

yea, i have that problen too. when i shot monsters or something else, i give that strange triangles on the distance instead of circles. and it not depends what fov you use

Novum commented 5 years ago

This is the original behavior of glQuake too. It's drawing one triangle instead of two for each quad. When I ported from QuakeSpasm I used that path because it was easier. Will fix it at some point.

spasm0000 spasm0001 unfortunately the problem is not completely solved, this is what quakespasm looks like vkquake0003 vkquake0000 and thats vkQuake

Rikoshet-234 commented 4 years ago

looks like a problem with alpha blending in the shader

Rikoshet-234 commented 4 years ago

because quakespasm looks absolutely normaly when r_quadparticles set to 0
