Atualmente estou fazendo um jogo (em vb.net) que usa oClasse de gráficos para desenhar a maioria dos objetos do jogo, mas eu corri para o antigo problema de desempenho. Para combater o atraso, adicionei algum código para diminuir automaticamente a qualidade do jogo para que eu possa tentar aumentar a velocidade do jogo. Isso funciona até certo ponto, mas mesmo assim o jogo fica mais lento quando mais "inimigos" são adicionados ao jogo. níveis mais altos. Eu sou novo na classe de gráficos (só comecei a usá-lo há alguns dias), então as únicas coisas que sei que ajudam a acelerar o meu jogo são: desligar Anti-Aliasing e diminuir o intervalo de Timer (que praticamente rege meus jogos taxa de atualização), então além do anterior, existem outras maneiras de melhorar o desempenho do meu jogo?

Captura de tela do jogo ...

Aqui está o meu código até agora (o bit de ajuste de qualidade está na parte inferior),
