    indoor/outdoor engine.., some feedback please

    Hi guys

    Can you please give me some benchmark on the performance of the engine ? It's an hybrid quadtree/portal rendering.
    I don't have a clue on how the interpolation models behave on another computers because they are linked to the frame rate .,so i would apreciate some feedback.
    And, if you think if it would be a playable game in your machine regarding rendering speed.

    the link is: http://brunomtc.no.sapo.pt
    thanks

    Bruno

    Re: indoor/outdoor engine.., some feedback please

    My PC: P3 @600MHz
    128MB, 100MHz sdram
    TNT2 m64 32MB, latest 12.41 drivers

    default settings; 800*600*16 etc.

    frame rate outside 40-50FPS
    inside 70-80FPS
    animation is very choppy on gun.

    When inside when near the guy FPS drop < 0.2FPS!!!!! at this point it sometimes also crashes or sets the player position on top on the ground?

    Collision detection is a little choppy, sometimes you can walk through parts of walls, pillars, steps etc and sometimes you can look through the walls.

    slightly annoying poping with the terrain.

    Nice lighting and good looking terrain and sky. Well done, I had an idea like this using portals to link the outside and inside to allow windows and doors etc. Is there any AI, I saw the guy walking about??
    Keep up the good work.

    Ditto, sometimes the terrain popping was severe. Only other things odd I noticed were some blending errors with the flares. For example, if you stand in a position that puts a flare sufficiently close to the line of sight to one of those particle system torches, the torch become obstructed. Also I could see the background of the flare texture blending with the scene. You can completely cut out the flare background with an alpha test. My machine specs: 700 MHz Duron, TNT 6.50 Det3, 256 MB. Oh also is there a run key? The place is so huge I wanted to run around but could only walk.

    I have an Athlon 600MHz, Geforce256 running det6.50 (or something like that), 128 RAM. I ran the demo in 800x600 fullscreen 32bpp, frame rates stayed around 90-100 sometimes getting to 110. One time though there was a sharp jert as i turned very quickly. There are some graphical glitches that can be fixed. All in all well done!

    Thnks guys,

    Tim Stirling:
    I'm having problems getting the animation look good. My problem is that i lock the frame rate at 60 for 800x600, but if the computer runs slower than 60 the interpolation on the models fails completely and gets weird...
    Yes, there is some basic AI, just testing some stuff.

    DFrey:
    Those blending errors happen because i'm not sorting the transparent surfaces before rendering. When i sort them, that effect should be gone. Yes, you can run with the F5 key.., not exactly run, more like hyperspace run

    MrShoe:
    Pretty high fps you get., on my Athlon 900 Mhz, with a Geforce2 mx at 800x600x32 i only get around 60.

    thanks everyone,

    Bruno

    Won't work at all for me, it just displays the loading mesage and then crashes. I have an Athlon @900MHz 256 Meg RAM and a GeForce 2MX with 12.41 drivers running Win2000.

    Ok, I looked at it again, and those blending errors I was speaking of can be easily fixed by disabling depth writes when drawing the flares and other transparent things. I also noticed a clipping error this time. If you stand too close to a corner inside (e.g. at inside corner at a turn in the hallway), the corner appears to get clipped by the near plane. I would either offset the bounding plane of the walls a bit more, or try pulling in the near plane (and far plane) while inside, and push out the near plane (and far plane) while outside.

    You all seem to have GeForce!

    20-30 fps on my Celeron 500, Intel 2mb onboard card.

    It crashes on startup (the replacement .exe also).
