Custom Spinner Lag

I think this is the right board for this. Sorry if it's not. >.<

Quite a few beatmaps with custom spinners have been showing up lately. That's all fine aesthetically, but my PC seems to have a problem with them. When the map loads it up for the first time, I always receive a period of lag that lasts for about a second. (As a note, subsequent uses of the spinner throughout the rest off the map don't lag at all)

This problem isn't much of a consequence in easier maps. However, in harder maps, the creators usually place a hit circle right at the point where the first spinner appears. The lag starts, and it prevents me from tapping the hit circle at the proper time.

I'd appreciate it if someone could help me out?

I have issues with spinners now and then as well. Some people experience that kind of lag with storyboarded maps as well. Only thing I can really say to do is just pause and retry.

This map has been deleted on the request of its creator. It is no longer available.

How much RAM/video ram do you have? Spinner sprites and the likes are all loaded at the beginning of the map, so should not cause lag unless they are being paged out of video ram, then out of system ram to disk.

For example, for the Men in Black beat map, Pasonia recommends that the player delete "white.png" if he or she is unable to handle the strobe effect the story boarding produces. Can the same thing apply to any other custom sprites and images the beat map might have (in this case, spinners)?
Yes. For now, anyway. You can delete any image files without consequence.

osu! seems to suffer from lots of performance issues from pagefiling when left running for a while.

There's definitely room for improvement in its memory management, but, for the meantime, exiting and restarting osu! seems to fix it. (Or you can put up with the jerks and wait for them to clear themselves up.)

This is your PC, not osu!. osu! keeps anything it is using in memory. It cannot keep all sprites loaded, as this is quite a large footprint (especially when skins are involved). If you are experiencing swapping, this is because you have been using other applications while osu! is open, which have forced osu! on your disk. I cannot stop this, as it is an operating system metric which works for the best.

All sprites for gameplay are cached at the beginning of playing and loaded into video card memory or RAM where that is not possible. If you are experiencing swapping DURING gameplay, you do not have enough RAM for the number of needing applications you have open. Try shutting stuff down or upgrading your RAM.

I believe osu!'s memory management is next to perfect, to be honest.

Maybe keeping everything in RAM is the problem?

The paging tends to happen right at the beginning of the countdown, when certain notes are being hit, and when the first comboburst appears. It's suggestive that these graphics/sounds have found their way to the pagefile. If osu! had unloaded them in its idle time, then only reloaded them once you started playing the map, they shouldn't have ever seen the pagefile and this wouldn't have happened.

Again, I only see this when I walk away and leave osu! idling for a period of several hours. Restarting the program or just putting up with it for a map brings all the afflicted resources back into RAM and the problems go away.

All game sprites are already reloaded into video memory at the start of playing a map. Can I ask how much video memory you have?

256MB.

(Also 1GB system memory and a 1.5GB pagefile.)

Again, this only happens (for me) if osu! has been idling for many hours, which just screams paging.
