been looking around various places, like you do

 

and found these:

 

[GRAPHICS]

MergeDirtyRegionUpdates=1

DirtyRegionUpdateLimit=500

 

what do these setting do and do you need them?

 

 

Thanks

This is a tweak that helps with panel updates, especially the glass panel. If you use the glass panel and notice very slow updates. There is a 2 part tweak:

 

[GRAPHICS]

DirtyRegionUpdateLimit=<integer>

 

By default this UINT32_MAX (i.e. four billion or so) so it has no effect.

Setting it to zero effectively forces full texture updates instead.

 

Setting it to smaller numbers (1-1000) might improve performance if the card is slow at full texture updates and does not have a high overhead for incremental updates.

 

[GRAPHICS]

MergeDirtyRegionUpdates=<0/1>

 

By default this is 0 (i.e. disabled) so it has no effect.

Setting it to 1 (enabled) causes us to merge all of the dirty rects into a single large dirty rect. This means that we will only do a single partial texture update.

 

This may work well if the card is slow at full texture updates and does have high overhead for incremental updates.

Thanks Ian
