GZDoom benchmarks - next round

[The Ultimate DooMer]

I can't select radial fog, only standard. (and I remember being able to on older GZDooms)

[Graf Zahl]

What card do you have?

[DaniJ]

I use occlusion query to reduce the load. Apparently this only stalls my card - for whatever reason...

I would suspect that you have GL error reporting on, whilst everyone else will not. Its worth checking to see if this is the reason why your system stalls.

Also, I would double check when and where you are doing the VBO updates. Mixing VBOs with occlusion queries AND immediate drawing during the same render frame requires very careful attention as it would be very easy to induce the GL process to block.

Are you attempting to use a handful of large VBOs for the entire map, both updating and drawing from them during the same render frame?

[The Ultimate DooMer]

What card do you have?

256 meg X1300 Pro. (was waiting for my pw to be sent out so I could upload my test screens to the DRD file server but it never came)

No, error reporting is off.

The occlusion query is only used on very specific portal setups. Interestingly these maps (only SSD) did not have any problems on ATI cards at all.

It does get updated in the same frame as it is used but never in the same range. All parts that get updated won't get used until the next frame. I'm using glMapBufferRange with explicit flush and unsynchronized access. This works fine on my system.

I would suspect this as a likely problem spot for ATI.

[Graf Zahl]

That's one of the reasons why the VBO is not used with ATI anymore. The other being that it doesn't improve performance.

But that's pathetic. What I do is precisely what the GL_ARB_map_buffer_range extension was designed for. What's the use of it if it doesn't work?

[DaniJ]

I may be wrong but my guess is that ATI is not segmenting the VBO into uniquely accessible blocks according to the ranges you specify, which would naturally result in either a block or a duplication of at least the changed ranges.

A potential cause for a performance lapse here is if you are accidentally writing outside of the range you specified as having been changed.

[Graf Zahl]

Unlikely. All tests were made while no changes were ongoing. I made sure for all benchmarks I posted that there's no monsters around that could activate any sector movement.

The only real problem I had was that on some older cards the update did not work.

[DaniJ]

In that case I don't know what else to suggest. If I think of any likely causes I'll let you know.

[Nash]

Is it normal to get 1 FPS at the very first map in Phobia: The Age? o_O I can barely play the thing.

[Graf Zahl]

No, it's not. Can you make a benchmark of that level? I need to see where all the time is spent.

[Nash]

Apparently having lights.pk3 autoloaded causes it. Here are results with lights.pk3 loaded.

Code: Select all

Map MAP01: "Phobia - Riviabolo...",

Graphics settings are all exactly as your benchmark requirements, except with the addition of gl_vid_multisample=8. Setting this to 0 doesn't change anything. 1920 x 1200. All settings in my ATI Catalyst are at factory defaults.

I'll do the full benchmark tomorrow... I've just finished downloading every prerequisite WAD.

[Graf Zahl]

Yes, Heavy Dehacked use and dynamic lights often don't mix well. Phobia uses one of Doom's lamps as a non-lighting item - and obviously this creates problems because there's just too many lights in the map.

So to all those who complain that lights.pk3 is not part of gzdoom.pk3: Here's one of the reasons why.

[Nash]

I see. Well, I went ahead and did a full benchmark anyway because I couldn't sleep. I've done my part...

System:
Windows Vista x64 (all latest updates installed)
Intel i7 920 @ 2.67 GHz (stock settings)
3 GB Kingston HyperX DDR3 RAM @ 1033 MHz
1x ATI 4870 X2
ATI Catalyst 9.10

GZDoom settings as per instructed, except gl_vid_multisample set to 8. Setting this to 0 doesn't seem to change the results. Screen is at 1920 x 1200 fullscreen. ATI Catalyst settings at factory defaults.

Using GZDoom 1.3.11.
