View Full Version : Effect of Canopy Glass on Game Performance

S! All,

I'm running Pacific Fighters on an older platform (Athlon XP 1600+, GeForce 6200 (but AGP 4x), 1 GB RAM), so I was always trying to tweak my in-game settings to get maximum output.

I was wondering why I'm getting 150% better FPS on external views than in cockpit with some aircraft and today, while flying an F4U, I noticed that <span class="ev_code_YELLOW">my FPS went up 60% when I just opened the canopy.</span> Then, I tested several aircraft in one mission in QMB and found that <span class="ev_code_YELLOW">with some planes I get more FPS in the cockpit (about 35-40) and with some planes less (18-22).</span> Worst performance was with these planes: Spitfire, F4U, P-51C, P-47 (D-10, D-27), La-7. Other tested planes gave good game performance (Ki-43, A6M, Yak-9, Fw 190, P-51D, P-51B, P-40C).

Although not all results fit into my conclusion, I think that some planes with canopy containing a large piece of curved glass put large demands probably on the graphics card due to either 3D model of the glass or lighting effects on it. I tried to adjust some video settings and the conf.ini file, but with no effect. <span class="ev_code_YELLOW">Turning down the canopy glass effect, if possible, could add more than 50% FPS in cockpit of certain aircraft on older computers.

Any idea how to do it?</span>

There is FPS loss inside cockpits, because the game engine is rendering a whole set of the details contained within that cockpit (polys and textures). Some cockpits are more demanding than others. What, for instance, is the performance hit on the extremely highly detailed I-185 cockpit?

Next question: Are you running S3TC texture compression? Do you have a key set to toggle mirrors on and off....are your mirrors on? Mirrors are present on most or all of the planes mentioned there and may infact be the cause of your FPS loss as there are large sweeping curved pieces on virtually all of those aircraft which in my mind doesn't make much difference either way to performance.

I doubt its the canopy glass. I'm somewhat convinced that its probably the mirrors.

It could be his/her setup, although I have never had fps problems with the FB canopy glass modding.

Except LOMAC, general flight sim glass "reflections" are static and don't move with the aircraft/sun or change with time of day, often have too many deep gawdy colours -- again static -- and most harmful, reduce the amount of external light coming through the canopy by 50% or greater, thus making sunset/sunrise landscape totally dark and the stars vanishing because of light absorption -- this is best seen in sims that allow turning on/off the canopy "reflection" during gameplay. Of course, the "reflections" are only Betty Tested during bright sunlit 12:00 Noon missions. http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

This is caused by computer monitors not being able to simulate depth of brightness or intensity of light and the human eye's ability to adapt to astronomically vast changing light levels. Same applies to the arcade looking gunsight glasses, which often "too dark" to be usable. The slight darkness was there in real life, but when modded on a shallow depth brightness computer monitor, the effect takes up a far larger percentage of the monitor's available brightness range and so steps between the simmer and sim in the most brutal way possible -- crippling visual interaction with the sim.

The one exception I have seen may be LOMAC dynamic canopy scratches that simply turn sparkly bright depending on angle with the sun -- so no artificial light absorption. Internal cockpit lighting reflections are well done too -- perhaps a bit overdone -- but I forgot if these are visible even if cockpit lights are off during the day.

If they must use light absorption to model canopy glass http://forums.ubi.com/images/smilies/51.gif they should just not model it at all until computer monitor brightness range increases several hundred times.

You are doing pretty good with that rig actually...... I had something similar but with a R9000 at one time... http://forums.ubi.com/images/smilies/25.gif

The only way to turn down the canopy effects is to use open pit view (I hate the term wonder woman view) from what I understand.

Me too Linda Carter does NOT deserve that.

Thank you all for your replies. Especially to you, Icefire, because you solved my problem. It's not the canopy glass, it's the mirrors. I turn them off and my FPS jumps up 60%. Thank you, Icefire! http://forums.ubi.com/images/smilies/11.gif

Yes, I'm running S3TC compression because it's recommended, but I haven't observed any difference when I switched it off.

The I-185 cockpit doesn't cause problems - I get slightly less than with the others (about 35 FPS against 40) a small difference in comparison to the difference between planes with mirrors and without them.

As for the performance of my rig in general, it's not good at all. I can fly simple missions in QMB, but campaign missions with plenty of aircraft, ships and flak bring it down. I started a campaign with the F4U on Iwojima and FPS remains between 5 and 15 http://forums.ubi.com/images/smilies/16x16_smiley-indifferent.gif I run excellens settings - turning it down isn't helping (+2 FPS on low settings), as well as resolution adjustment.

No cockpit view... well, I was always flying full real and HudLog off, so I don't think I would accept it http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

Thank you once again, it helped a lot!

Yeah, for whatever reason the mirror (which I like) absolutely kills frame rates, even if you happen to have an Athlon 64-3500+, 2GB RAM, SB Audigy 2ZS, and GF6800 Ultra PCIe rig as I do. With the mirror on, heavy action becomes a slide show for me, mirror off and frame rates don't seem to drop below about 40 with perfect settings, water=1.

Glad I could help.
