Greetings.

I modified the Quickres.ini in a way that it features now some more 
resolutions without and with AA. One of the added resolutions is 6400x4800.

- I parsed a scene and had the beta version 12a rendering this scene which 
worked pretty well.

- Then I wanted to re-render with the same resolution which caused an "not 
enough memory" error message.

- I selected a smaller resolution, rendered, re-selected that previous big 
resolution and was now able again to render.

This makes me thinking that there is, maybe, a small programming error which 
only frees up the memory when the resolution is being changed, am I right? 
On my system, that error occured only with re-using that big resolution.

My OS is Windows XP Media Edition, Intel Pentium 4 @ 3.06 GH, 1.25 GB RAM.

Greetings,

Sven

Did you have display preview turned on ?

I can confirm that I cache the previous bitmap so that POVWIN doesn't need to
re-allocate the memory if the render resolution does not change; and it does
appear this is overlapped with the destruction of the old one. I'll have to
look closer as to how I could fix this (the data in question is held via a
shared pointer and as such it's not possible for me to just delete it in-
place; I have to chase down where it is normally released).

Hi Chris,

yes, each time I render, that preview is on. At least, for the first 
minutes.

Another problem I saw is that error messages seems to be truncated (bottom 
of the window).
