Speed tests

Post by **Graf Zahl** » Wed Aug 31, 2005 13:59

I am really interested how the engine performs on different computers. If you are interested to give me some information please do the following:

1. Start GZDoom with PAR.wad (Phobos: Anomaly Reborn)
2. go to the console
3. type 'MAP E1M6'
4. type 'vid_fps 1'
4. type 'kill monsters'
5. without moving or turning go to the console again and type 'warp 180 -1750'
6. Observe the frame rate counter in the bottom left corner for a while

Then post this number with your system specs (CPU, graphics card, amount of memory and driver version.) in this thread.

If you want you can repeat the test with ZDoomGL's light definitions.

Ok, with dynamic lights on I get 50fps, without them 70fps. Resolution doesn't seem to matter.

Specs:
GeForce 6600GT (overclocked to 550/1020)
AMD Athlon 2500+ (overclocked to ~3200+, 2.09ghz)
1024mb RAM
nVidia 77.77 driver

That's more than I get with a Geforce 6800 with a P4 3.2 GHz and that card is definitely faster than the 6600GT I had before. I get 36/60 fps at that position... How is that possible?

Strange, could the p4/amd difference be it? I really don't think the video card makes a difference here anyway, the cpu is more likely to be the fps-limiting factor (as I said, it runs the same speed on 640x480 and 1600x1200)

Who knows? But the CPU is not the only limiting factor here although it is the biggest one. From that position I got moderate increases in speed between a Geforce 5900XT, 6600GT and 6800.

Just out of curiosity, could you go to that place again and then type 'stat rendertimes' in the console and post a screenshot of that? That should give me more information.

Showing the rendertimes lowers the fps a bit

It appears to be your CPU. The overall setup time is half a ms less than on my system and the overall render time (which also contains some significant overhead to set up the data) is almost identical.

So much for Hotwax's claim that AMD is cheating their customers with their numbers.

And the only precalculated geometry I am using are the x,y coordinates of the subsectors. Everything else is done each frame again.

Hehe, looks like I'll be sticking with AMD for a while then

I would have, too, if preinstalled computers came with Athlons. Too bad that Intel has a monopoly in that market here in Germany. To get an Athlon with the same performance I'd have to go to a dealer who builds his own computers and then I'd have to pay more.

Believe me, I am not a big Intel fan.

Heh, here it's generally cheaper (and better in the long run) to buy parts sepeartely and build your computer yourself

I bought an AMD 2000+ w/gf2mx and 256mb ram originally, then upgraded it bit by bit until what I have today (the old parts I sold to my brothers, works out well

).

System:

Athlon64 3000+ @2.4GHz
ATI Radeon X800XT Cats 5.8 (500/500MHz)
Geil Value PC3200 2x512MB (1024MB)

GZDoom 0.9.2
Resolution 1280x1024
64fps with Dynamic Lights on
76fps Without Dynamic Lights

Edit: I also used 4X Anti-Aliasing and 16X Anisotropic Filtering

Looks Like GZDoom Is VERY Cpu bound

I think I need a new computer.

Not bad, those numbers.

How do you get ZdoomGL's light definition?

I managed to get 50FPS in 1024x768 resolution without dynamic lights (I don't know how to activate them

).

My spec:

Asus K8V SE-Deluxe motherboard
AMD Athon 64 2800+ (socket 754)
ATI Radeon 9200 SE (Yeah, I need to upgrade that

)
2x Kingston 512K of PC3200 DDR RAM

Looking good

Get Lights.zip in Downloads and plonk Lights.Wad in /skins.

That graphic card is a little weak for that system, isn't it?
