[2.0.05] Bug : Game lags on first rendered particles

[pagb666]

This happens to me since 2.0.05. Every time I run the game, the first time particles that are rendered in-game, I get a huge fps drop to 0. After particles are rendered once, then everythin is silk smooth until the next time I start gzdoom.

I'm running win8.1, i7 950, GTX660ti. Tried upgrading my old ass video drivers from last year, and it didn't help-

Have you tried to see if the different particle types make a difference? (Display Options/Open GL Options/Preferences/Particle Style)

[pagb666]

Just gave that a try. Only happens with 'smooth' particles... which I've been using for years without any issues.

Are you using any texture scaling?

[pagb666]

Don't know which particular option are you referring to, so I'll just paste this

gl_texture_hqresize_targets=7
gl_texture_hqresize_maxinputsize=512
gl_texture_hqresize=4
gl_texture_format=0

[Graf Zahl]

gl_texture_hqresize=4

means you have 4x upscaling on. That might be the reason for the hiccup.

gl_texture_hqresize=4

means you have 4x upscaling on. That might be the reason for the hiccup.

Yes, changing it to "0" wiped the hiccup... and now my sprites look ugly.

Don't know what has changed in 2.0.05, i've been running "4" for years with no issues.

Confirmed on GZDOOM pre-1159 (gfbefe13) with Hexen.

There's little that can be done here. The precaching logic can only catch textures that are being referenced by something, so once anything with an unprecached texture comes into view, some small delay will happen because the scaling algorithm is quite costly.

[siealex]

And what about precaching ALL textures, especially if the PC has a lot of RAM?

[Graf Zahl]

Then your graphics card will most likely explode.

With 4x upscaling there is no such thing as 'sufficient RAM'.

this happens to me too, been playing with smooth textures and 4x upscale. didnt know it was a gzdoom thing though, i just figured it was from one of the wads i autoload or something. anyway to me its not that big a deal, i just shoot my pistol at the beginning and then its all smooth from there.
