Having issues with slowdown

Hello, I picked up Supermodel a couple days ago and I've been having some issues with it. I'm a bit of a noob when it comes to more advanced emulators so I apologize in advance if there's some really obvious fix I never figured out, but here goes:
So I should mention first up that I'm using the Model 3 UI frontend and the Warped Polygon preconfiguration. I booted up Spikeout Final Edition, and everytime I've tried it there's been some major slowdown. The menus run just fine, but once it gets to or even shows actual gameplay it slows to a crawl. I got my computer a RAM upgrade yesterday, and since then it's been....somewhat better but still pretty bad. I redownloaded it from somewhere else afterwards and it had the same issues, so I don't think it's a ROM issue. The PowerPC frequency settings are set to 75 by default in this config, so I fiddled around with it, such as lowering the number or getting it up to a more accurate setting for a Step 2.1 game such as this, and I did notice changes but it stayed pretty slow regardless. To see if it was a game-specific issue, I tested Virtua Fighter 3 and it had the same issues so it's a wider problem. I acknowledge that using preconfigs designed to have your work cut out for you probably makes this harder to get to the bottom of, and I am sorry for that, but this has been kind of a headache regardless and I wanted to ask around.
Here are the specs:
CPU: Intel Core i7-7700
GPU: NVIDIA GeForce GTX 1050 Ti
RAM: 16 GB
So yeah, I'm kind of at a loss as to what this could be here. Is it a configuration issue, is my computer too underpowered, I don't know so I'd like to get this out there and see if there's anything that can be done. Cheers
