Slow start

Post by engelbrekt »

Hello everyone,

I've noticed that my program now takes about a minute to start, whereas it used to launch instantly on the same machine. The exact same program also runs fine on two other machines.

The only possible cause I can think of is the latest Windows update. I've already tried reinstalling the C++ Redistributable, DirectX, and GPU drivers, but the issue persists.

Is anyone else experiencing this problem?

I'm running Windows 11 24H2 (26100.3476).

Best regards

A 3D-simulation using OGRE as it's 3D-engine.

I think it is hard to say what could have caused this, but as it only happens on your computer and not anyone elses, you can profile your program to see why it takes longer time to start for your computer.

That way, you will find what has changed. It may be that your computer is for some reason not reading files as fast as before (or that the program is now on a HDD instead of an SDD, which slows down reading it).

Just basically add profiling to each and every line of your startup code (as in, output the time between all calls and resource loadings and such).

Your computers antivirus (or Windows Security/Defender, which is the built in one for windows) may also make it slower. So try to turn that off first and see if it returns to its normal startup duration.

OK, so in a way you are asking if anyone else who uses OGRE is having trouble with the latest Windows 11 update.

What version of OGRE are you using?
What rendersystem?

What does the OGRE log say?

In my case I'm staying with Windows 10 because I know that 11 is trash, so can't help you there.

But with the OGRE log and some profiling as @rpgplayerrobin says it might be possible to find a solution.

Uninstalling software from ASUS fixed the issue. I did'nt bother pinpointing which software was causing this. Some other issues unrelated to OGRE was also resolved after doing this.
