FPS reports (version 7, 7a)

[Dr.Sid]

Hello there. I'm interested in your FPS values, using the last demo:

Commanders Academy & Dive Center - Forum - View Single Post - Progress (http://www.commanders-academy.com/forum/showpost.php?p=21145&postcount=8)

Please report CPU, GPU, RAM
Then FPS at start (when window has 800x600) and FPS at any resolution you use it (together with the resolution, of course).
Report both without changing the view. Just run the demo, wait few seconds till FPS stabilizes, that will be the first value. Then max the window, again wait few seconds .. that will be the second value.

Something like this (my values):

Intel Core 2 Duo 1.8GHz, 2gigs RAM, nVidia 7300 go.

At start: 53 FPS
At max (1280x1024): 34 FPS

[goldorak]

Intel Core 2 Duo 2.4Ghz, 2 GB ram, ATi 1950pro (AA 4x, AF 16x, Triple Buffering enabled).
At start : 59 FPS
At max (1280x1024) : 55 FPS

[OneShot]

Intel Core 2 Quad 6600 @ 3.0Ghz, 4GB RAM, XFX 8800 GTS 512 (AA & AF set to Auto)

At start : 76 FPS (no difference above or below water and sub stopped or underway)
At max (1280 x 1024) : 76 FPS (again no differences)

[Molon Labe]

7 FPS default resolution, no change when maximized to 1024x768.

3Ghz CPU
2GB RAM
GeForce FX5200 GPU
(Not exactly a 733t rig, I know. DW has never been a problem though, although sometimes custom models like that of the Duke FFG load slowly)

FPS 16

[Dr.Sid]

Hm .. 15 ? That's bad, even if it is old card. On the other hand I use pretty basic techniques at the moment. CPU-GPU transfer is the problem, but there are methods how to avoid this .. will try.

Open 11 FPS
@1024x768 11 FPS

[Dr.Sid]

I'm at half of the way of cpu-gpu transfer optimalization and I've got from 53/34 to 74/41.

[Dr.Sid]

This is new version. It is only optimized version of sim6. It also allows to change some things. Hopefully this version will get nice FPS for everybody.

http://roger.questions.cz/other/sim7.zip

New features:
- indexed meshes, full use of vertex buffer objects where available (should be pretty much everywhere these days). This decreases amount of data transfered into GPU each frame. Effect may vary depending on what is the bottleneck on your system, anyway it should help somehow. At my system it gives 150% FPS, fullscreen mode (same window size) gives 200%.
- yes, you can turn fullscreen mode with alt+enter. It now only switches into 800x600. It should help at those very lo-fi systems. Anyway you can test if fullscreen works correctly for you, and if alt-tab to desktop and back works correctly (it should).
- you can change draw distance, use keys F1,F2. It can go from 12.5km to 200km, default is 50km. This changes amount of terrain drawn, it should have major effect on FPS.

I'm in the low 30's now. It was hilarious as I drove my 688 thru the Akula...can't wait for the collision model! ;)

30 at basic setup, with no fullscreen and no draw distance change ?

Btw. you are great tester group. Now I have report from high-end GPUs, low-end GPUs (sorry), even non-GPU chipset. :biggrin:

[sonar732]

yes...I just opened the application.

[goldorak]

The increase in performance is unbelievable :biggrin:
Same settings as before,

At start : 280 FPS
At maximum (1280x1024) : 196 FPS

[Dr.Sid]

yes...I just opened the application.

Fine .. there is still room for improvement, this optimization was in method of rendering. But for example terrain is still 'monospaced' it means the mesh has same resolution near camera and at maximum distance. This is quite simple to do but very wasteful. So I hope I'll get even better FPS (and I have to squeez some other stuff there too, like actual simulation:wink:)

Just for your info, memory amount being transfered each FRAME at various draw distances:

12.5km : 838 kb
25km: 1234 Mb
50km: 2752 Mb
100km: 8555 Mb
200km: 31477 Mb

With vertex buffer all that should just stay stored in GPU and no more transfers are needed. Of course in case there is enough memory in GPU and so on. It's really cool what this hardware can handle these days.

[Molon Labe]

I'm up to 30 fps at default resolution, dips to 19 fps when maximized and switching from above/under-water view (recovers within a second of the view angle change).

[OneShot]

At default I'm still at 77 FPS, The only drop I have is when switching to the 200km View Distance, then it goes down to 59 FPS.

EDIT : Now I know why I only got 77 ... VSync was still enabled. Without it I get the following :

at Start : 667 FPS when moving around and switching views it plays around 660 +/- 5 FPS
at Max (1280 x 1024) : 620 +/- 5 FPS

No differences above or below water.

12,5km : 1000+ FPS
25km : 900+ FPS
100km : about 220FPS
200km : 58 FPS

[Dr.Sid]

667 ? Omg ! :eek:
Good point with the VSync. And with the water. There is no reason to draw that much terrain under the water. Anyway in optimizing performance I'm always interested in the worst case scenario.

[Shadows_Fall]

Start: 14
Maximized @1024x768: 12
Zoomed in to normal playing distance: 13
Submerged at normal playing distance: 16
Submerged with bottom in sight: 16
Submerged with bottom not in sight :18

Oh, and going into full screen just locked the sim up. It never did anything, just showed me a black screen. ALT+TAB worked normally tho.

What is your OS ?

[sonar732]

I went ahead and switched my VSync off also, but didn't notice a change. Depending on where I am in relation to the subs, I'm +/- 5 FPS.

EDIT: After playing around a little bit, I noticed that the prop stops on a dime when you select 0 knots. Has this been discussed before?

[Shadows_Fall]

That's pretty weird. I can move all around the sub, and my frame rate never drops.

[Dr.Sid]

Yeah, the simulation now is pretty basic. It's not supposed to be correct in all aspects at the moment.

[OneShot]

Turning off VSync wont help much unless you have a system with a lot of power (in regard to the game you wanna run) because VSync works as sort of a bottleneck. With VSync you only get as much FPS as your current refresh rate for your screen. In my case since I have a LCD I have it set to 75Hz Refresh Rate which turns out to be about 77FPS in the CSS apparently. If your FPS are below your Screen Refresh Rate then you dont have to deactivate VSync (it wont help).

25-31 FPS
