Just to note, the latest version of Sega Model 3 UI (04/10/2022) only allows 1 as lowest value.
Users can always manually delete the option from the Supermodel.ini.
This doesn't work. Sega Model 3 UI will just create the same PowerPCFrequency entry again once you open it. Is there any way to get around this issue?

The author of the UI needs to fix that.

I would not be understanding this exercise of adjusting the automatic PPC... it is advantageous and logical for PCs that run supermodel without performance problems. I guess it's because some games need more hardware than others, it's 2024

If you have a super PC I don't think you need to lower the frequency at which the processor works...

For me it's about accuracy. I have a very high-end PC but still want to use the automatic frequency setting. Raising the CPU frequency wont get me higher frame rates anyway being as these games are locked at 60fps and already run perfectly at their intended frequency. It also helps newcomers because it's one less thing they have to worry about. The manual frequency setting is becoming less and less relevant as hardware gets faster. Any remotely recent hardware will easily run Supermodel.

Automatically setting the PowerPC frequency to match the emulated game is the correct behavior and is what Supermodel should have always done. MAME would do this, for example.
Here is the easy way to update your UI:
- Add a checkbox above the frequency slider: "Override PowerPC frequency". By default, this should be *unchecked* and the slider should be disabled (grayed out). In this state, either set PowerPC frequency to 0 in the config or remove it altogether.
- When the override option is checked, allow the slider to be used, and then set whatever the user wants.

Frankly, I only use it once and never open it again. After the initial setup, it's easier for me to directly modify the Supermodel.ini. I use LaunchBox anyway as my frontend.

I upgraded my CPU to a Ryzen 5 5600x. This fixed the flicker and can now run Supermodel at full speed.

A simple solution for people having problems with the UI might be to just use 166MHz as the speed. Have not tested but games should be fine as they all measure clock cycles taken by a frame and are therefore relatively clock speed invariant. 166 is what Step 2.x need anyway and itβs a surplus for the other games.

That is a good tip. Thanks Bart.

So is it certain now that Step 1.5 runs at 100 MHz?
