poor FPS Qrack, r_dynamic

[ungod]

when i turn on r_dynamic i get a massive performance hit, depending
on where i am looking FPS can drop down to 9. When r_dynamic is off
FPS is good and stable around 100+ but i cannot see the glow around
someone that has a powerup like Pent or Quad, so right off it puts me
at a disadvantage. i have tried several cvars to see if i could somehow
keep the glow effect without having r_dynamic on but i have no success.

I remember i had the same problem with JoeQuake. with my old ATI 1900
still getting the same thing with a new ATI Radeon HD 3850 AGP.

anyway to trick it into getting back the glow with it off?

[metchsteekle]

i beleave "r_powerupglow 1" is a help because it put a shell around the player/object that has a quad (or is coded to have so it looks cool)

or was it "r_powerupshell 1"? eather way on the vweapon the sell should be colored, but not on anything else

i would suggest going to the qrack site to find the real ansure

i tried those Papasmurf but thanks anyways.

basically i just need the powerup glow effect back without taking a huge
performance hit from r_dynamic thats generating dynamic lighting and glow
from all other light sources for example: flames, muzzleflash, explosions, etc.
apparently my rig cant handle all that other stuff.

sounds impossible i know but thats what i was asking.

r_dynamic is a big performance hit indeed.. fitzquake suffers from the same problem.. and my guess is so does joequake, not glpro however!

maybe someone can get into the details and explain why?

Hmmmm - looking at the QRack source (1.85), I see that he's using my interpolated light animation function, which means that lightstyles will get updated every frame (by default Q1 updates them at 10 FPS), so that's quite a performance hit to begin with. It might be useful to make this toggle-able, just for folks who have slowdowns with it. Moving further out, he's uploading lightmaps in his texture chain drawing function - I've found it more economical on some cards to do a bulk upload of all modified lightmaps before even drawing anything. It's extra texture binds for sure, but it more than balances out.

Another trick is to stick a few glFlush () calls throughout the code. This keeps the OpenGL command buffer moving along while you're doing CPU work; effectively simulating a separate rendering thread. It won't give much of a speedup in general use (although I did get about 10 extra FPS from it), but it will help prevent (or at least reduce the effect of) the occasional logjam. I generally do a glFlush () after each texture in the texture chains, after each alias model, after each group of 128 or so particles, and so on.

glFlush after each lightmap upload (remember - uploading in bulk before rendering) helped too, as otherwise you'd have to wait for glTexSubImage to do it's thing and the new lightmap to become available (I might be talking rubbish here, but it seemed like the right thing to do, and it certainly didn't hurt).

I can't tell right now if his R_AddDynamicLights function has the common bug where a lot of surfaces are marked as dynamic by R_MarkLights but don't actually get their lightmap updated. This can result in quite a few unnecessary lightmap uploads. It looks like his dlight list trick avoids this, so it's probably not the case.

Overall, the best optimisations come from how you structure your code. Do a batch of GPU work, then flush, then a batch of CPU work, repeat to fade, and everything will keep pumping along smoothly.

I've added a cvar to toggle light interpolation, I'll have to dig thru the code for optimizations as more than 80% of the code is passed down from id, quakesource.com, open source projects, etc... it might "work" but it's not a fluid code base by far The only piece of code that really craps out my 8800gt is the rain code < 100 fps at 32768 particles! Ack. well its immediate mode so its better than per pixel lighting in tenebrae jk I'll take your advice and see where things can use a flush.

I get little to know performance hit with r_dynamic on. I have a radeon 9800 pro 128mb video card, so i'm not sure what the big difference is.

Try my entire config file, see if that helps at all.

not many maps have lots dynamic lights on them but for the ones that do, r_dynamic 1 is a big fps hit on qrack and fitz.. glpro works just fine.. (try my pegdm6_beta1 map for example)
