[Survey] How many of you CANNOT run GZDoom's OpenGL renderer

[Gez]

I might as well be playing straight ZDoom with this setting on.

Basically, yeah. Only difference now between GZDoom in software mode and plain ZDoom is that dynamic light actors placed in a map will be merely without effect in GZDoom while ZDoom will spawn error markers.

[Slax]

Only problems I've had with GZDoom was on a budget Geforce card. Cheap desktop, performance so bad it was unplayable.
Works just fine on my 560 Ti though.

I can run Gzdoom fine even though i have an intel GMA unless im playing a mod with heaps of effects on the screen at once (Brutal Doom, AEoD)

[bgraybr]

I've got a AMD Phenom II x4 (something like that), and a Geoforce GT240 and I've never had any bad problems on either operating system, even on resource intensive mods with all of the filters on and whatnot. Some major slowdown if I do something ridulous (like play nuts.wad with Brutal Doom and all the filters and particles turned on) but no real problems.

I can run in a pentium 3 1GHz, 1GB ram and a nvidia fx5500 agp2x.
I only disable some opengl settings, i only not disable dynamic lights (i change the heigh to be a little that was in original) fog, textures suport.

I can run Hunters Moon without lag (depend of the map, some biggest ones it lags) AOW lags in many maps,zombie horde i play with nice fps, Dawn of Reality 0fps all the time, ghouls vs humans runs nice (except the last one nordic saga map, with snow) I can play Zdoom Wars fine, I can play project msx nice in simple maps (lags when granade explode) and i can run my own mods =D

My home computer has a modded 9800GTX+ and can run Crysis, so it's obvious it can run GZDoom perfectly fine. A VirtualBox VM I have with Arch Linux can also run it, but with a slightly lower performance.

The computers we have at school run it rather crappily depending on what WAD you give them, sometimes they totally freeze and have to be restarted. I guess it's because they are all Dells with Intel GPUs.

I'm pretty sure it also ran fine on my old computers. The newer one with an integrated GeForce 7050 (which ran UT3 at 5FPS, from what I can remember) and the older with a 5200 FX Ultra that was capable of miracles.

Woo-hoo!

Spoiler:

I'm an ATI user.

[Edward-san]

Can't run it because my notebook graphics card faulted so I'm relying on Ubuntu failsafe mode (no opengl).
There's no warranty so I don't have the time and the money to change the motherboard right now.

Yay! Now the graphics card is definitely broken!
When I turn on the pc, it emits one long beep and two short beeps after.

Now the pc is in some technicians' hands in order to see if they can do something (still I don't like to buy a new pc, I don't want to inquinate the planet because of a card's fault). It means no programming, no compiling, less using internet.

[JimmyJ]

I can run it fine on my desktop, which has a quite modern ATI card I can't remember the exact specifications of, and my laptop, which uses integrated Intel graphics I'm stuck on since my desktop's mobo is currently burned out.

[riderr3]

I can say YES, but, on my system PRBoom runs much faster and smoother than GZDoom (ATI, 256 mb)

And I can not see shaders menu (strange, but I saw that menu in Skulltag)

[RV-007]

Welp, my graphics display adapter somehow died on me (by either hardware or software). It was so bad, that any graphic-extensive application caused a BSOD or reboot. I decided to shut the graphics card down and I'm playing/modding for VGA-friendliness now.

GZdoom still works w/o the display adapter support, but there are fuzzy tv specks that goes around.

No GZDoom doesn't run fine at all. Radeon HD6, and don't blame "AMD Driver are a big shit" for coding incompetence. I remember when this used to run fine on a Voodoo2, hell, a Doomsday build could run better on a Trident Blade.

[tsukiyomaru0]

GZDoom Engine consumes wayy too much memory to render things. To the point it causes Blue Screen of Death here (XP SP3, 3+3ghz, 3gb RAM, intel graphics card with tons of limitations). Funny enough, many other games worked here under different conditions. Tron 2.0 had slowdowns when too many polygons were on screen, PSX emulator runs fine with no slowdown or "lag" (and allows for a very accurate speed booster), NO$GBA is able to render most games with little to no "lag", DeSmuME varies a lot, Project 64 can handle it well depending on the plugin, and so on.

[Enjay]

Curious. I suspect the problem is mainly your graphics card. I can run GZDoom pretty happily on my old computer with is XP SP3, a single 2.8GHz processor (IIRC), only 1GB of RAM (which was huge when I bought it) and an NVidia 6200 (again IIRC) graphics card.

Can you do it better? Don't throw around words like 'incompetence' when you don't have a clue about the things you talk about. Makes you sound like an idiot. Also, where's the port that does it better? The only one is GLBoom+ and the reason for that is solely that it has to deal with a lot less baggage from the core engine.

Also, don't forget that most of the code is 10+ years old from a time when there were no vertex buffers, no shaders etc.

The ATI problem is actually very simple: ATI's drivers need too much time to execute immediate mode commands. The engine, however, was made at a time when this was the only means to use OpenGL. Changing it now would necessitate a complete rewrite of absolutely everything.
