Target Framerate and Tri-Linear Filtering

[Flaps30 3]

Could someone please tell me what the target framerate really does and what is its advantage? Also, what is the difference between bilinear and trilinear filtering? I've tried both and don't see much difference other than a slight difference in framerate. Thanks.

If you don't have a target framerate the sim will render as fast as it can. This means that the framerate may vary quite a lot, depending on how complex the scene is. If you don't understand much about real time environments, you may think, hey, it's best to leave it at max. However, setting a cutoff framerate has an advantage and that is smoothness. It's quite 'disturbing' for our brain to get visual feedback at different rates, ie 10 fps one second, 50 fps the next, and this can even lead to motion sickness in some cases. Having a constant framerate will appear much nicer and smoother. Ideally of course you would have a framerate of 75 or even 100 (ie your monitor refresh rate), but even with modern hardware you can't get up to those frames with FS2002.How to set this value? Enable your framerate readout and observe at what framerate FS2002 typically runs on your system (eg 20 fps). Set this as the maximum. This will mostly supply you with a constant framerate and should be more comfortable than constantly jumping between 15 fps and 40 fps...Trilinear filtering gives you a slightly better image quality, especially for textures that are far away...Cheers, Christian

Thanks for the info Christian! Tom :-beerchug

Christian: I've wondered about this question myself from time to time. Thanks for the detailed explanation. How does one go about enabling the framerate readout?Cheers, JEH

Shift - Z a couple of times.
