Annoying framerate issue

[Xalthorn]

Okay, I'm getting very close to reinstalling this computer because I don't what windows decided to install, but consistent framerates are disappearing.

The most recent annoyance was when I downloaded the desert strike cracktro from retro remakes because it looked stunning.  It ran like it was on speed... way too fast.

Does anyone know where I could look to try and see why my machine refuses to cooperate any more?  I used to be able to view demos knowing that the framerate would be fairly true.  Now even the stuff that ran smoothly before is going way too fast.

Xalthorn, I think you have turned off V-sync on your graphics card.

The desert storm intro has no delta timing, it was one of Stormbringers first and it uses Opengl.

So you need to check your settings for your card and make sure that it is enabled, that should fix the problem for you

Hehe, not guilty, but windows might have done something that it considers 'optimising'.  I know that when the machine boots, after windows loads there is a brief video black out which I assume is it making some setting.

I'll start digging though, that certainly sounds a fair bet.

Look in active desktop (right click on desktop)
Settings
Advanced
Adapter
Set Opengl to be application controlled.

Apologies if this sounds patronising, I hope that the problem is this easy to fix for you, the issue is certainly v-sync. I'd bet my house on it.

Don't worry about appearing patronising, you'd be amazed how often the obvious is overlooked...

I have no such OpenGL option in the adapter settings, so I'm still digging around.

[Xalthorn]

Woo hoo!

Shockwave strikes again

Yep, I had to dig around the ATI Catalyst control centre (never run that before and I'm definitely not guilty for the change).  The Vertical wait was set to performance (always off), I set to quality (always on) and suddenly everything behaves properly.

Silly computer

Excellent Glad it's fixed!

Excellent Glad it's fixed!

So am I, strangely enough, my older demos run properly as well now
