I have a little question, excuse me if this is just talked, is this new TKG exe better than old TKGPatch ?
At least for a standard A1200 + Blizzard 1230/IV ?
I believe the current build is significantly more performant. Amipal did a comparison video he posted a few pages back.

The comparison to V500 and V1200 would be interesting because those are also slowed down by the real chipmem bus. Once the Pi can utilise the chipmem bus to its maximum throughput, it will certainly beat the Vampire accelerators. The V4 will probably still come out on top and could only be beaten by a Pi-standalone or WinUAE.
My take is that even if the max frame rate is slower, the FPS consistency over time for the Pi will be better. The C2P time is essentially constant, depending only on the screen area copied. The frame calculation varies significantly depending on scene complexity and that's where faster computation will win.

Personally I'd rather have a rock solid 25fps than swings of 10 to 50.

@abu_the_monkey

Can you get a PR ready for this instrumentation?

I'm thinking to add a build flag soon so that you can build a fully instrumented version and a release version that doesn't include any of it for the best possible performance.

Better to have 2 version, one for test purposes and one without data speed on screen for full performance.

Anyway I'm happy with this latest build. It has better performance on all my Amiga systems respect to original and TKGPatch executables.

Well done !

Can't it be done with a togglekey in game?

It can. I suppose it comes down to wanting to be able to have a build that's as streamlined as possible. Also, there aren't many function keys left

I have now raised a PR but it probably needs a tidy up and a proper check from yourself or pipper as I may well not be doing things in the most efficient way.
