The speed increase is pretty impressive, but I've found problems... (groans)
The new patch is completely ignoring vsync on my system, I know what my system can throw out, and that's a maximum of 160fps, but my current project is throwing out 250 and everything looks jerky because it's not synced with the monitor refresh rate. Plus the sync rate command has become inaccurate, I ask for 80fps and it gives me 90. With the problems in patch 4 and the previous patch I can't bring myself to enter my project into the competition knowing what bugs exist that I can't do anything about.
After reading the above I'd be surprised if what I've programed will even work on everyone's systems. Heck, it's amazing DBPro works at all considering what it's trying to do!
