Lagging and Glitchy Playback... Please Help!

Question

I'm so frustrated with Premiere at the moment that I;m considering switching to Final Cut. I have a project due for a client by tomorrow morning at 8am and I literally cannot put one effect on a clip without the render bar turning red. Playback is then not possible unless I re-render the effect, but the moment I add one more effect it does the same thing... This only recently started happening. I have edited multiple 10-15+ minute projects in the past with no issues. Premiere glitches like this from the first clip I try to edit. I am no computer guru, but I do have a lot of editing experience. Any help is greatly appreciated because I honestly don't know how I'll finish the project at this rate.

My computer specs are below:

-iMac Retina 5k 27 inch

-RAM: 32GB 1600 MHz DDR3

-Graphics: AMD Radeon R9 M290X 2048 MB

-Using footage from a Canon 5DSR, Sony HXR NX5U, and a DJI Phantom 3 Advanced. No 4k footage, so there's absolutely no way my computer doesn't have the specs to handle it. It's something going on with Premiere. As stated, I've had no issues in the past and am doing nothing differently this time around.

Thanks in advance for anyone taking the time to help.

You don't mention what drives you are running on, and how connected to the computer. That could be an issue, especially if a spinning drive in use is above 60% utilization.

I would note, the cameras there shoot in codecs that are possibly all heavily compressed long-GOP, that require a ton of CPU/RAM work for the de-encoding. DSLR and drone footage are of course famous for this. While the iMacs look pretty, I've not been that impressed by the performance people have been getting with them ... there is clearly a heavy price in hardware parts in order to make it all fit in that small space behind the screen. So you've got a middling unit (comparatively) running some hardware-intensive codecs.

If it's handled this exact mix of footage & effects in the past better on this version of PrPro, then ... I'm curious again about drives being used, connections, that sort of thing. I'd normally assume you're on SSD's with something that minimalist for space, of course ... but would need hard data to make any wild guesses.
