Do you use the tweak SWAP_WAIT_TIMEOUT=xxx with DX10 Scenery fixer?

[Jedi928 6]

Is this tweak available Under dx10 scenery fixer or not?

 

Thanks for your help!

It's nothing to do with the DX10 Fixer, Jedi. 

 

SWAP_WAIT_TIMEOUT=2, taken from several different sources:

 

This setting affects the loading of textures. It is the number of frames that the above process will have to wait before assuming a particular tile has been already loaded into video memory.

 

If SWAP_WAIT_TIMEOUT is set too high, then FIBER_FRAME_FRACTION (no matter if it is set to 0.99) will have to wait X number of frames before attempting to read a tile/texture from video memory. This will cause stuttering.

 

If SWAP_WAIT_TIMEOUT is too low and the requested texture has not yet been loaded into video memory you will see a white flash.

 

It's size will depend upon GPU speed & memory, against the graphics pipeline speed. 2 is where mine sits at this moment.

That is good to know. Thanks for the thorough explanation.

What is the default if not in the configuration file?

I think it's 3.

Bojote had published 30, but I don't think that's applicable any more, given the increased speed of hardware. One can try any number of course! Too big should cause stuttering - try it! Experiment - that's how these things become recognised as a good tweak - or a waste of time......   :lol:

 

All the best,

I'm currently using SWAP_WAIT_TIMEOUT=30 in DX10 with the Fixer, and it is smoother now, and I think (but not sure) that fps is  a little bit higher on approaches and finals.

Lower the SWT-out until white flashing begins - then up it by one. Mine is set to 3, as it was when using the 580. Remember - it's tied to the FFTF setting - which will cause stuttering when too high, and ground texture blurring when too low.

[Pe11e 812]

I have FFTF at 0.15, and SWT at 30, and everything is perfect. No stutters, no flashes. But I have a problem with lens flare and contrails (flashing and dissapearing), and I'm not sure is that problem connected with fsx.cfg at all.
