Simple Performance Boost

<< < (3/4) > >>

Samson:
I use ClearType and can confirm with the default settings on Simple Performance Boost, ie leaving smooth edges of screen fonts unchecked, that ClearType works fine,  :smiley: hope that helps?

Willy2:
I need to elaborate. In fact there's no problem at all. In order to find out what changed in the registry with visual tweaks I switched off all options (i.e. chose ""best performance"") in Windows (XP). And by switching one separate option on at a time I tried to find out what changed in the registry when I changed one option. So, I ruined my original settings but the way Windows stores those settings is VERY complicated. Then I restored the original settings using XP and not SPB.
And ran the ClearType applet again. That's enabled/controlled by ""Smooth edges of screen fonts"" ??

I unticked the box ""Visual Tweaks"" (above ""Apply Tweaks"") because I didn't want to disable all visual tweaks that are controlled by that one registry key. But now after using my laptop for a while I think I'll go back to the ""best performance"" setting. And then I can tick those boxes with ticking only one box.

In XP, right click on the Desktop>Properties>Appearance>Effects>Use the following method to smooth the edges of screen fonts>select ClearType is how I set it up, and to adjust ClearType I have the tuning option in control panel http://www.microsoft.com/typography/cleartypepowertoy.mspx. So, yes I think ClearType is enabled/ controlled by enabling "Smooth edges of screen fonts".

I suffer from a mild visual impairment, and have found that making the contrast darker within ClearType helps to overcome this. Thanks to my Optician for the tip on this one  :wink:

Willy2:
In SPB there're 7 options that can't be (un-)selected individually because they share all the registry key. I found out what the individual values are. One has to go down to the bit level to see the changes. Looking at the HEX level doesn't make any sense. When all those 7 options in SPB are NOT ticked (all effects enabled) then the mask is 9E 3E 07 80 (Hex).

[HKEY_USERS\S-1-5-21-1482476501-688789844-854245398-1003\Control Panel\Desktop]
"UserPreferencesMask"=hex:9E,3E,07,80

But in binary it looks like 1001 1110 0011 1110 0000 0111 1000 0000 (8 groups of each 4 bits). And 7 individual bits control each one visual effect.

This is the explanation: (x = doesn't matter/didn't change)

xxxx 123x xx4x 56xx xxxx x7xx xxxx xxxx

When one of these seven bits (numbered 1 - 7 in the line above) is reset (""0"") then one particular effect is DISABLED. See explanation below:

Bit number X (1-7, see above) controls:
1: ""Smooth scroll list boxes""
2: ""Slide open combo boxes""
3: ""Fade/Slide menu into view""
4: ""Show shadow under mouse pointer""
5: ""Fade/Slide tooltips into view""
6: ""Fade out menu after clicking""
7: ""Show shadow under menus""

Please check/test the function of bits #1 and #2. I hope I got it right. I am not sure I did. Keyword: Translation.

Shane:
Very nice!

I will look this over. If it is at binary level I should be able to update the program so it knows what to set everything :-)

Makes me wonder why on earth MS did it this way.
