Olá Filipe Deschamps! Tudo beleza?
Eu recriei o algoritmo do fogo do doom usando Compute Shaders, isso faz com que todo o algoritmo fica para a GPU, aumentando drasticamente o desempenho até em dimensões maiores do fogo em computadores mais modestos (o meu computador tem o Intel z5-Z8350 com gráfico integrado, bem fraquinho mesmo e conseguiu rodar em 60 FPS um fogo com tamanho 512x512 sem travar momento algum).
O problema é que como é um recurso experimental (mas funcional), só consegui fazer rodar nos meus testes no Google Chrome Canary (acredito que funcione no Microsoft EDGE Insider Channels) com umas flags habilitadas no chrome://flags (#enable-webgl2-compute-context, #use-angle e #enable-unsafe-webgpu).
Na página dá para mudar o fator de resfriamento, o fator de calor na base do fogo e a direção do vento. Mas eu tenho planos para adicionar mais coisas como mudar o gradiente da cor do fogo, mudar a resolução e o fps durante a execução, etc.
Abraços!!
