Intel HD 3000 slow in skulltag

[ibm5155]

Sorry i couldn´t test the laggers mods in gzdoom because the don´t run on it =/
they is azkos city and jump maze 2 map33.

Why i´m posting this? because the same maps runs with much more fps in a geforce9400gt.

Intel HD 3000=>12 unified pipelines, core350-1350MHz shader core:350-1350MH, DDR3 memory.
Geforce 9400gt=>16 unified pipelines core 450MHz shader core:1100MHz.

geforce 9400gt on quake 4 ultra:39FPS
Intel HD 3000 on quake 4 ultra:49FPS

Doom 3 on ultra
Geforce 9400GT:83GPS, HD 3000:48FPS

Left 4 Dead on high
Geforce 9400gt:23FPS, HD 3000:72FPS

Racedriver:Grid on medium
Geforce 9400GT:17FPS, HD 3000: 26FPS

Fear 2 on medium
Geforce 9400GT:27FPS, HD 3000: 32FPS

Quake 3 on maximum
Geforce 9400GT:240FPS, HD 3000: 242FPS

So here am I, why is the reason for the HD 3000 be slower than a 9400GT in big and detailed areas?
and another two questions, the fog shouldn´t up the fps and not lower?
and why in radiant fog 3D weapons get strange lights on it?

That´s it, i hope i didn´t your time ^^

Your question is not easily answered. Obvioulsy the hardware can't handle certain things as well as others but that's not something that's easy to find.

Out of curiosity, how does GZDoom fare on a larger map? You just say Skulltag is slow but how about some actual values? Also, Skulltag's renderer is quite far behind. GZDoom has been optimized quite a bit since they updated the last time.

Running the biggest map that i could run in gzdoom and skulltag (dawn of reality) i got 11fps on gzdoom and 13fps looking on skulltag (both i add hunters moon, for the models take some fps) i take a print and both was in the same place i took...

I think the problem of the lag is the large numerous of sectors that player is seeing, i don´t know why i got less fps in a newer gpu (intel hd 3000) than an older geforce9400gt...

Graf, the bsp create the map ok, the sectors are done by gpu or processor?

[Graf Zahl]

Newer != better.

Also, the drivers make a lot of difference.
NVidia's drivers are known to be well performing with GL in immediate mode and large numbers of state changes.
AMD, on the other hand, has a lot more overhead in its OpenGL calls that easily make a performance difference of 2 graphics card generations.
Intel doesn't seem to be good at this, either.

So with modern Intel or AMD cards such old fashioned engines tend to perform much worse, especially on large maps.

newer gpu (intel hd 3000) than an older geforce9400gt...

A new Intel vs. an old Nvidia? Heh.

Who would run the fastest, a newborn turtle or an adult race horse?

[DaMan]

Try turning off all shader effects. IIRC Intel's EUs double as TMUs as well as shaders.

[Graf Zahl]

If the card reports SM4 the only way to do that is to start with -sm3 on the command line.

here is my test on gzdoom with D.O.R
PS:change the resolution´ll not affect in fps

---

All shaders on + fog radiant:15-16fps
All shaders on + fog standart:15-16fps
All shaders on + fog off:20-21fps
All shaders off + fog radiant:15-16fps
All shaders off + fog standart:20fps
All shaders off + fog off:20-21fps

things that i note, models and dynamic lights don´t affected the fps drop
screenshot from the same place with hunters moon (not tested)


Graf, do you still have the gzdoom benchmarks for testing?

All shaders off + fog off:20-21fps

These values are a clear indicator that the limiting factor is the OpenGL driver.

I reuploaded the benchmarks. Here's the link:

I'm not sure if the savegames are compatible with 1.5.06. If not you need to download 1.5.03, which you can find here:

Sorry for the late repply, but the link is broken >.<

[Graf Zahl]

Sorry. I don't know what happened. Unfortunately I lost the files due to a HD crash so I can't reupload them again.

[ibm5155]

I did some more tests and i discovered somethings, in map23 i got 23 fps in 1024x768 O_O (looking to all the barrels)
And in big maps like the jum maze map33, i got 25 fps, but if i disable the textures i got 60fps O_O (dynamic lights, filters, quality/speed and fog didn´t change more than 2fps)

Could this be because of the gpu ram?

[Graf Zahl]

No idea. Good news in another way though. I found my benchmark stuff on an old CD. I'm going to upload it so that you can do some tests with maps I know.
