Frame rate: This is the number of complete pictures a second that are displayed. Think of a frame meaning whatever is contained inside a picture frame. 24 FPS means that there are 24 complete pictures created per second. 2. Refresh Rate : This is the number of times a second that the display device rescans the picture on the display device. In a CRT device, as I stated in my previous post, the refresh rate needs to be at a minimum , greater than 45 hz so that the viewer won't see flicker. The faster the better, until you get to a limit that is dependant on the decay of the phosphor on the CRT. When FS9 creates 15 FPS per second, as it may do when all sliders are maxed out and some AI generated, the refresh rate of your CRT monitor does not also slow down. It remains at whatever your graphics card refresh rate is set at. For example , if FS9 is generating 15FPS, and your monitor is refreshing at 60 hz, each frame that FS9 is creating will be refreshed or scanned 4 times. This refresh rate should guarantee that the vast majority of viewers will not see flicker in the image. The ceiling in refresh rate comes when the refresh rate doe not allow the phosphor to decay ( or go out) before the next refresh. Special CRT's are used in Stereo Video that have fast decay phosphors, because stereo video has refresh rates that can run up to as high as 100. http://www.answers.com/topic/frame-rate>>And...like you said that you can never get any higher fps than>the refresh rate on your computer.

Becuase I have bad eyes and a crummy system and I run the sim at 18fps and it looks fine to me therefore nobody needs more than 18fps. :)

Hey thanks for taking a look. I think you are the only one, which is a pity. I found the measurements interesting on how bogged down Windows can get for a gamer.-Todd

"I'm not so sure about the 48 fps on showing a movie,I've never heard that but...with film 24 is fine because the projector is ALWAYS running at 24 fps--it doesn't jump around to 12 then to 32 and so on."http://www.broadcastpapers.com/hdtv/GVGDig...20-%20print.htmHDTV - broadcastpapers.com"Film projectors run at an information frame rate of 24 frames per second (fps) and a display frame rate of 48 fps due to the double flashing of the shutter."-Quote from the URL above. "Ignorance of a fact doen't make it false." -MeThe jumping around factor has nothing to do with smoothness. Even film at 24fps isn't very smooth. Go watch a movie and watch when the camera pans quickly. It really doesn't look that good at all. Just pan in VC and see if you can read your radio numbers. (King Air/VC). AT 85 fps, those radios are totally readable even with a pan rate of 900. Anyway, doesn't matter. Many folks don't understand this whole frame rate issue and difficult at best to explain it. It has to be seen.Scott

I will say this,That any FPS below 18-20 directly effects controlling the aircraft. I find the response effect on landing is really apparent at about 14-16 FPS. So any time you can squeeze 5-10 FPS improvemnt, TAKE IT!I really hope that M$ releases the XBOX 360 "optimized" version so we can FLY rather than TWEAK!Barry

Greetings Barry,You should take a look at my earlier post. You can get your 5-10 FPS with software alone.You can find my results here:http://www.digitalthemepark.com/downloads/...FPS_Testing.pdf- Todd

I'm gonna jump in with my 2 cents....I agree it's nice to say " Hey man, I get 687 frames per second on my boss machine". But.........If it not fluid, it's not worth a toot. I find that fluidity is in part based on the Varation in frames. If this line is added to the FS9.cfg in the MAIN section:AVE_FRAME_RATE_DISPLAY=1The last figure on the screen that shows the frames is the varation. It's the V= xx.x figure. I find that if this figure is lower than V=3.0 the sim will be fluid and smooth. High varation rates mean that its really working the cpu and Vid card.I have mine set so the V=xx.x is 1.0 or lower. I can pan at this setting a full 360 without a pause.. Also flying is very smooth and fluid.You can run your frames up to 687 FPS if you want to, I'll keep mine where its really smooth.Joe W.

Please s'plain Lucy. Which software are you referring to for that 5-10 fps increase and what does it do?

Greetings,In the PDF I note the software applications and procedures that I used. I did not want to hack away at my current desktop to optimize, since all sorts of stuff would stop working so I employed FirstDefense-ISR to "create an empty snapshot" to install a new instance of Windows XP, then strip it to the bones. You can find the write-up on how to do this here: http://leapfrogsoftware.com/support_info/a...GamingBuild.pdfI takes time to setup, but as you saw in the results it was well worth it.-Todd

I think he is referring to his FirstDefense-ISR software, which after reading the PDF, you can come close to the same results using the FSautostart program by Ken Salter I believe. I really don't see the results as that big since lots of other variables come into play inside FS to effect the FPS.Regards, MichaelKDFWhttp://www.calvirair.com/mcpics/mcdcvabanner.jpgCalVirAir International

Yeah, if by "stripping it to the bone" you mean shutting down all unnecessary processes and apps, running bare minimum desktop settings (ie, no cutsie mouse animations, sound effects, bizzaro color schemes, themes, etc), that's all stuff I've been doing for ages. I think you'll likely find many of us do so. Doesn't require any third party apps at all actually...

Forget about all that technical stuff. We need high framerates because they are better than low framerates.Doug

We'll, we may have lost sight of my tests. I not suggesting that folks NEED to go out an use a 3rd party app. (but they do make live a boatload easier) I just wanted the folks that have not taken the time to optimize their systems, whether it be with an application or manually, to see the differences. I read a lot of posts with a lot of folks having issues. I figured (mistake?) this could be my little contribution by having a bit more scientific approach as IsmetM mentioned.btw: I have used Ken Salters product for some time, good app.-Todd

Why does one assume that high frame rates and choppy motion(fluidness, or lack thereof) go hand in hand? High frame rates and fluid motion are possible, and it doesn't take a $5000 Alienware computer to do it either.

I agree. As a matter of fact I would love to trade high frame rates for fluidity but it just doesn't happen. I lock fps lower but I don't get and improvemnt in fluidity - I would even say I loose fluidity.Michael J.WinXP-Home SP2,AMD64 3500+,Abit AV8,Radeon X800Pro,36GB Raptor,1GB PC3200,Audigy 2http://www.precisionmanuals.com/images/forum/747400.jpghttp://www.hifisim.com/images/asv_beta_member.jpg
