After a couple of testings I could confirm that the source of the massive slowdowns on DX 5 and 6 games is some alpha textures. If I force no alpha textures in International Rally Championship, it'll run smoothly (this disables smoke and headlights). I wonder if anyone is working on a fix for this, or could, with this information.

I've been doing that in the last 3 years, but nothing has been done so far. So I hope on 3rd parties now.

Well, sometimes, they say they forward the feedback to their team, but I wonder if they actually do.

Good to see you here. At least I'm sure what causes this now. If I knew programming I would've sorted this out.
