Significant framerate drops while scrolling.

[pirodaggar]

Hi I'm just wondering if anyone else is experiencing problems like this. The bigger the level, the larger the slowdown (sometimes slowing to 5 FPS), and the only conclusion I can draw from it is that it has to do with Windows Vista (32 and 64 bit). Are there fixes for this? The hardware in the machines I've tested it on are more than capable to handle a 2D game of this magnitude, it just seems to be something with the way data is handled.

Yea you get lagg while Scrolling, especailly if you use paralaxing, in my First Person Shooter rotating the camera produces several times more lagg than walking or strafing.

What did you set your runtime display settings to?
There are 'Standard', 'DirectX' and 'DirectX+VRAM'. Try changing between them and find one that doesn't cause slowdown.

Andos,

DirectX causes a little more slowdown, DirectX+VRAM causes significantly more. Run at machine indepdent speed causes jumps but less lag.

no word on anyone else with similar issues? I assume this happens to a lot of people.

How many layers do you have in the frame? Because of the way that the collision masks (I think) are processed, if the majority of action (collision detection and so on) on the frame is above the first layer it can cause speed problems, especially when combined with scrolling large playfields.

Try 256 colors, just a thought, and it may help.

[pirodaggar]

Only using one layer, changing to 256 colors doesn't help. Thanks for the suggestions though!

I'm assuming since two mods have replied with offered suggestions you guys don't get this much? Seems like all the vista users i've interfaced with have experienced similiar issues (although varying in frame drops, most likely due to the application's level size)

It does look like it's fairly unique, which is fortunate, but not for you Vista does seem to cause a lot of problems, but I haven't heard of it slowing down something so chronically. Is it definitely Vista - do you have an XP/earlier machine to test out the same application?

[pirodaggar]

I can test it out on an XP machine that's definitely worse than the current machine to see if I can get some higher fps than the one I'm on if you give me two days (: Currently not at my house so the only machine I have access to is my laptop. Just made a big level with only one active, so I think it now has to do with active's position on (or off?) the screen.
