Today I spun up a Fedora 14 VM, compiled SEQ there with the available library versions, and spent some time in-game. But still no luck reproducing the lag issue here. No matter what I set my FPS limit to (even 1fps) my render time never goes above 5ms.

Maybe you could try dumping some profiling data so we can see if something is taking a bunch of time that isn't supposed to? You'll need to "make clean", re-run configure with "--enable-profiling" (and any other flags you usually use) and then re-compile.

Then run SEQ, and once it starts lagging, wait some more so there's plenty of data, then exit out of SEQ. That will produce a file called "gmon.out" in the current directory. Then you run "gprof showeq > profile_info" and it will convert all of the binary profiling data in gmon.out into something that's human readable and put it in profile_info. Then if you can post that profile_info file here, I can compare it to what I have and see if anything stands out.

Thanks.
