FSX Phil Taylor's latest Tweak

Recommended Posts

Hi AllPhil Taylor has posted this tweak on his blog:"Try adding this to the [DISPLAY] section of the FSX.cfg file:ShadowMappingQuality=nwhere n can be 0,1,2,3.The 1st 2 values affect the size of the shadow map. The 2nd 2 values affect the filtering algorithm"Should the new line read: ShadowMappingQuality=0,1,2,3. or should it read:ShadowMappingQuality=1orShadowMappingQuality=2or, and so on.Its not very clear from the post but he does talk about the "first two values" and the "second 2 values". I suspect the individual settings but just want to be sure!!Any help would be appreciated.Peter Hayes

Peter, the answer to the riddle is in the structure:ShadowMappingQuality=nNote the singular "n"... ;)O or 1 will affect the size of the shadow map.2 or 3 will affect the filtering algorithm.

BillThat's what I thought It goes back to my "scientific" days when you clould use a "string' to denote "n" as well as a single integer.Any ideas on which number might be the best value??Many thanksPeter Hayes

I usually don't have shadows turned on. Would this tweak still help me?Manny

Manny,It's not a performance tweak ... but rather a visual tweak. Since you're not displaying shadows, such a tweak would have no effect on your experience I should think.Cheers,

Bill,If you are around and have the time I'm still a little confused around this issue.As I read it I thought that what he was saying was that there are 4 numbers:0,1,2,3"where n" (single number) "can be 0,1,2,3.""The 1st 2 values affect the size of the shadow map. The 2nd 2 values affect the filtering algorithm."What I thought he meant was 0,1 are the values which "affect the size of the shadow map".and values 2,3 are the values which "affect the filtering algorithm".Therefore as I (probably wrongly} thought either 0 or 1 will decide size and 2 or 3 would set filtering and that one would have to decide the parameter that they wanted to adjust ie.........either size or filter if "n" represented in fact a single numberClue me in please.

Maybe it's a two-bit binary value, where the first bit (0/1) controls the size, and the second (0/2) controls the filter? 3, of course would be 'both on'.

>Bill,>>If you are around and have the time I'm still a little>confused around this issue.Actually, that is precisely my understanding, and is what I stated in my previous reply:ShadowMappingQuality=1 OR ShadowMappingQuality=2 OR ShadowMappingQuality=3 OR ShadowMappingQuality=4In any case, I've written to Phil directly and asked him to clarify the issue. Either he'll chime in or I'll relay any reply I receive... ;)

The only other possibility I can think of would beShadowMappingQuality=0123as I do not see 'n' as being anything but a single value or as Tim pointed out, binary, but what I just posted would go against the structure 'n' as presented in the original exampleThe description would tend to suggest the 4 digit example aboveBueller? Bueller?

BTW Nick_N:What variables would be valid for "_N" in your forum name? :-lol :-haloGaryGB

It's just a tweak, no need to get so excited.It is just 1 value at a time, Bill is correct about that.Try them and see if you even notice a difference; its something I pulled from an old email from Sebby and he is no longer on the team so it isn't something I can check on faster than people interested can try on their own.

LOL!Thanks PhilI had posted the single digit explanation elsewhere but the description and the question around it got me thinking perhaps I was wrong tooYou do realize that one day you and a few others may get locked in a room by us and not allowed to leave until we get all the unknown config tweaks in a nice organized listor you have to convince us there really is no morehe he he

PhilThanks for your response. I certainly wasn't getting excited but I thought (and so did others) that your blog was ambiguous. It might be have been better if you had said:ShadowMappingQuality=n(Where "n" = equals any number from 0 to 3) . . . and then explaining the significance of 0, 1, 2, 3 (as you did) etcHowever, thanks again for the clarification, I thought that you meant one singlke number at a time but I just wanted to make sure by asking the more erudite mebers of this forum.FWIW IMHO FSX is the best flying sim that MS has released and it works well on my modest system.Peter HayesEDIT: Left out statements originally in square brackets!!

This from the ESP SDK info (http://msdn.microsoft.com/en-us/library/cc526948.aspx), down the page in "Configuration Settings" paragraph:"ShadowMappingQuality (set to 0=off, 1=Low, 2=High, 3=Auto - the default is "Auto"). The "Low" setting for the shadow mapping refers to the shadow mapping filter present in the RTM version of ESP. The "High" setting refers to a newer, higher-quality shadow mapping filter. By default, the higher-quality filter is applied if the Graphics slider in the Settings dialog is set to High or Ultra High. Use this configuration setting to override the default behavior."I'm assuming this is the same functionality described by Phil for FSX

Phil,Moving forward, would your team consider documenting more of these settings and/or coupling them with elements in the UI for adjusting these settings?It seems that new .cfg tweaks/settings are always emerging and the documentation is not centralized.Thank you,
