But those are different, that's just because the game needs those models, but a different game made in this engine obviously won't need a 3D texture for every letter because they probably won't use flying letters as projectiles.

Many people pointed out the floor, so I'll say this instead: Instead of sending an image for each color for the enemies, you can send a single, grayscale image and tint it by multiplying by a color based on their health. Sending data to the GPU is usually the biggest bottleneck, so this should speed things up a bit.

9:30 No. A CPU does do SIMD. They have registers of sizes up to 512 bits now (with MTX extensions coming that'll have 1024 or 2048 in the future), and instructions that operate on them as though they were packs of 64/32/16/8 bit registers, in a way it is similar to what GPUs do, but on a far fewer number of, but far larger and more pipelined, and completely out of order, predictive, highly optimized cores. Instead, GPUs use SIMT, Single Instruction Multiple Threads. A GPU is made up of (in nvidia's terms, every vendor calls them something else) many GPC's (General Processing Cluster) that contain many SMs (Streaming multiproccesors) that contain Thread Blocks made up of two Thread Warps, which are basically a pack of 32 execution units that can do memory, floating point or integer related instructions, but no decisions, those are made by the SM controller, and all do waves of the same instruction (or they need to stall if not all of the threads are meant to take the same execution path).

Yo to help with the floor rendering, add a UV multiplier into your base shader and you can gain back a lot of the performance from just using a single plane like you did previously, and scaling the floor UV texture.

I just realized that you have been able to make a lot of games with different programming languages, and I remembered today that when it comes to programming you need to focus more on being a great problem solver rather than remembering syntax, and I believe that will help you be able to learn any programming language. I learn't about this from Fireship's video, how to learn to code - 8 hard truths. Do you ever have any difficulties with making new games with different programming languages? And if not, do you think there's a reason?

All high level languages are basically the same, so it really comes down to what platform do you want to write a program for. Windows, c#, c++. Web, javascript. Linux, c, c++. Just want it to work and don't care how: python. But of course the most fun: assembly.
