Some (maybe nooby) questions regarding shaders, resolution, resizing etc

[gid15]

1. Is there any way whatsoever to get shaders working on ATI cards? I think several games may need them to display correctly without glitches, am I right? For instance in FF: Dissidia I'm getting lots of triangles and square boxes for certain effects. If I try to enable shaders on my Mobility Radeon HD 4670, no games will launch at all (resulting in some java null pointer exception error).

Different results have been reported for ATI/AMD cards with shaders (http://www.emunewz.net/forum/showthread.php?tid=3894). The results depends on the selected Jpcsp configuration options, the version of the catalyst driver and the hardware. Try different combinations.

For the null pointer exception error, please post a log file at INFO level.

2. How does the resizing / resolution changing actually work. I guess resizing just resizes the window size. Does the resolution change the internal resolution the game is running at (and is there any performance cost in changing it? In other emus I can pretty much run it on the same resolution as my actual display, but Jpcsp seems to be limited to same scale the PSP uses).

3. Can I change the resolution and resize the emulator window WITHOUT messing up the game HUD and graphics? Preferrably without having to lower my own resolution? Usually I can resize the emulator window just fine in game menus, but in game it only displays a small portion of the screen.

Aredo is working on this (http://www.emunewz.net/forum/showthread....224&page=7), but this is currently not working on all applications.

4. Videos seem to stutter a lot for me, is it normal? Usually they will play fine with good fps at the start for like 5-10 seconds, then the fps will dip to around 10 and the audio will become messed up. I have media engine enabled with sonicstage decoding. And is there any way to improve it, like could I somehow decode the files fully in advance so the emulator doesn't have to do in on the fly?

You can use the configuration option "Media" > "Extract media files to tmp folder". The extracted files can then be decoded on your PSP using the JpcspConnector (instructions how to proceed are displayed in the log file).
