I know tier two is faster than one but by how much on average?

I'd guess tier 2 C/C++ is probably dozens or possibly 100+ times faster on code (logic) execution assuming the exact same code pattern is implemented in both versions.
I wrote a couple small programs for code execution speed comparison a year ago. One in C#.Net and one in AGK2 tier 1 (actually did a Blitz Basic version as well) and the C#.Net version was much faster. As in many times faster.

And considering that is C#.Net is compiled into IL (basically we can see this as what AGK2 tier 1 is compiled to) and then the current fragment (which is great for loops and so forth) is JIT (Just In Time) compiled into native machine code and a compiled C/C++ program won't need to do that JIT compilation during run-time C/C++ would be faster than C#.Net. How much faster? I don't know. Maybe 50%. Maybe double.

However, this is only for the program code we write. When it comes to graphics both tier 1 and tier 2 should be using the same AppGameKit libraries which means that aspect should be performing at the same speed in both. And generally in games it is this piece which is the bottleneck. However, any time saved on code execution will provide additional time to render more graphics.

Hope that helps a bit anyway.

writing an array of 1280 x 720 is in c++ 65x faster at my pc

at phone with tier1 basic copying 2 hd images together with memblocks commands take 4-5 seconds ...

That's about what I'd expect. Say 50+ times faster on average for pure code execution. Good to have it tested instead of theory though. lol

Thanks for the input was just trying to work out if it might be worth learning tier 2 and it appears it would. 50 times faster is a huge amount.

The more important question is - do you need the extra speed? It comes at the cost of speed of development and complexity of code, as C++ is a fickle beast to partner up with.

Plenty of apps these days are written in - of all things - JavaScript. A hacky awful language designed and released upon the world from the inner bowels of Mordor. This is interpreted at run-time as well, much like AGK. And much like AppGameKit, it is no speed-demon compared to say C/C++, Rust or Go - all compiled languages really. Yet due to Angular/React frameworks hooked up to Electron run-time JS allows rather pain-free cross-platform app development using known and widely used web-technology.

And it works. And devs don't turn mysteriously hairless and shivering in angst-induced horror in a dark corner uttering again and again "I just tried to compile for ARM, I just tried to compile for ARM, I just...".

For high performance apps/games - and certainly for heavy-traffic backend infrastructure, speed is key. But in all other cases, you should offer a friendly thought to all those hardware engineers who have so kindly made modern computers so fast that we can happily waste most of their resources on rather inefficient high level languages. In the name of keeping sane, happy and meeting deadlines

@Dybing makes some great points.

And keep in mind like I mentioned in my reply above. Tier 2 is not 50+ times faster than Tier 1 period.

It is 50+ times faster executing the code you write.

In itself that is irrelevant. If your game runs at full framerate in Tier 1 then writing the same game in Tier 2 will provide no benefit. It is already fast enough in T1.

If the major bottleneck is the amount of / quality of graphics being rendered you won't see a 50+ times increase in speed. Because the rendering should be basically the same in both T1 and T2.

I'd guess that increase in code speed may result in anywhere from 20% to 3 times speed increase or so in real terms for an actual game. Because again... the execution speed of your code is only one part and generally the graphics rendering is the biggest issue in all game engines. All of those graphics being drawn is usually where the real bottleneck is especially with added load of custom shaders and such.

FPS takes a lot of advantages and disadvantages

if FPS runs at 60 - that a nice speed

If you set FPS to start at say 600 - and let your world come into play - this may knock it down to 30FPS

so you have to compensate for FPS inreases and decreases when moving around you app.

Cause your players will move frantically if FPS runs at 100 but runs really jerky at nice at say 30FPS

Dropped because of the amount of things you put in

i had only speed problems in image processing with basic, but mind agk is for games.
the other one was recursion for ai at a board game - unfortunately too slow, but i still can tranfer this project into c++

developers with c++/c#/java/swift/database/web/... knowledge are highly coveted. its not wrong to learn.

board games can be looped on sync loops with a

Thinking...

type of variable when true then goes into thinking mode but every other part of the app can still be accessed like pressing buttons instead of a terrible nested loop hang feel

Its about good structured programming to stop them hanging feels

Always keep in mind of nested loops and try to keep every frame going when one is going.

its not a hanging feel its about playing against a cpu opponent ai and nobody will wait 30 minutes for a move ... (and btw a too deep recursion will make agk crash)
me thought i can do a Nine Men's Morris (Mühle) AI in Tier 1 Basic but it was not possible because speed ...

@Markus,

but you wouldn't use an Array [x, y] for Image processing. You rather would use image-functions or memblock operations.

i would make a feature request to get image data into array for tier2 or using something in c++ that can load images into memory.
currently i tryed make video from light painting and after that i try to process pic by pic but can not step one pic foreward.
i used playvideotoimage , but if you process one pic which take a lonk time, the video skip frames and use real time.

I miss also a lot of the functionality, I am used to have in PureBasic. I also tried a bit with "Playvideo", but maybe we have to use external plugins or so, to decode Frame by Frame.

It would be also nice, to be able to have more than one Image-Render-Target. Logicaly. Combining and Composing new things, are a lot easier with PureBasic functions.

Maybe we have to make a tutorial about image processing and a "Photoshop"-like clone or Paint-like-clone.

I'm confused......why can't you image process in an array? I have my 2d space game using memblocks to alter large images really fast - where the player takes dance it alpha blends scratches, dents.....even holes with burn marks. That's processing 2 or 3 different images through a memblock before making an image and copying back to the sprite. On a small sprite (say 100x100) you can do this 30 times a second.

You can also have multiple render images can you not? I did a dynamic downsampling routine using a render image, while using another to do interface effects.

Is it AppGameKit now quite equipped in that regard?

not at phone, it takes 5 seconds to add 2 images in hd together.
the interpreter core is not that fast as you may think. you can do this in c++ in an array 100+ x faster

Quote: " On a small sprite (say 100x100) "

100 x 100 =10.000 pixel
1280 x 720 = 921.600
~ 100x more

The thing to understand, is that images in memory have to always be transferred to OpenGL as a texture for display - which is basically what the memblock functions do - they are not just moving images in memory.
