After the 1st try....BOOM BAM !!!! Again, the same issues as PD8 with the crashes, slow previews, and hanging. In addition, it is slower to render ( especially when changing the speed ). Have they not learn from this forum and the known issues??I then came back to this forum to find the answer. I followed all the suggested fixes, including updating the latest build and drivers. Still, the same issues.
After more trials, I decided to shut off the two " hardware " accelerator options and TURN ON shadow files. Bam ! It never crashed again and my render speed came back up. The results were excellent HD videos. Yes, its too funny. I suspect that if you " juiced up " your video card like I did, you need to turn them off in PD9, and you will still get the same accelerated results. Who knows. Its screwy. But my problems are gone. The shadow files being on indeed help my previews to be quicker and did not hinder anything else.
