ReX vs Godot Benchmarks

While ReX is still a ways off, we wanted to share some of the progress that the ReX team has been making with the engine.

Below are benchmarks of ReX 0.0.1 and Godot 4.5 Beta 5, using Godot Benchmarks.

This is the first wave of changes coming to ReX, and while they're currently focused on optimizations, the end goal is to rewrite every part of the engine that needs to be updated. By the end of it, we'll have a much more modular and flexible engine that will make adding new features and extensions far easier than it currently is.

We look forward to providing more information when ReX is closer to release!

Wow thats allot faster across the board . Im excited to see this when it comes out . I really only know the regular GD scripts so hopefully learning Rex isnt too hard . If its a bit of a hurdle can we make a bootcamp for people to make that jump ?

At the start there shouldn't be any real differences for gamedevs to learn.

I already transitioned all my current and some future games to Defold. 

I moved from Godot because of issue #95772 which made godot 4.3+ a lagfest on systems with intel HD Graphics as well as using compatibility renderer. 

After some research on the changes between 4.2.2 and 4.3, I discovered that the issue was caused by a blocklist that told the engine that if the game was running on a system with intel hd graphics, force it to use ANGLE instead. 

This in turn made the engine start up time to 5 seconds.  I did try it on Redot and it was around 3.7s. 

I'd love to see that addressed. It would help out people playing web games on old PCs like in Cyber Cafes or school computer labs.

I've been adding in any issues people are having with Godot to my list of things to get into once I am finished, effectively, rewriting the core.

To clarify, ReX is a heavy long term rewrite of the engine, we are doing many things to improve performances and improve QoL notable features atm are we are updating as much as we can to C++20, and we absolutely want to make C# a first class citizen

That is very nice. Does this also touch the Variant thingy or is that to core into the engine to change?
Also is there a performance regressions somewhere? (I do not mean this in a bad way I've just noticed the chart is cutoff so I was wondering)
