A GPU AMD Radeon usa apenas 384MB de VRAM em vez de + 2GB de memória de vídeo dedicada

Question

por algum motivo, a maioria, se não todos os jogos, está limitada a apenas 384MBs de memória de vídeo (VRAM), em vez de 2048MB de memória dedicada. Eu li em algum lugar que desativar "Sych with VBlank" no menu OpenGL resolveria isso, mas isso não aconteceu. Agora, qual poderia ser a causa disso?

Observe que todos os aplicativos 3D testados foram executados com o Wine 1.5.26, o PlayOnLinux 4.0.14 com o AMD Catalyst 13.1, 13.2 e 13.3-beta3 irá falhar ao acaso, informando que não há memória de vídeo suficiente ou que um erro de aplicações tenha acordo, o que faz com que a minha primeira impressão do Ubuntu seja extremamente improdutiva, limitada e mais importante não reproduzível.

Existe uma solução para este problema? Como faço para que o Linux ou meus aplicativos 3D percebam que há mais memória de vídeo dedicada disponível para o meu HD6970? Existem comandos apropriados para este tipo de problemas, ou existem outras aplicações como o Wine / PlayOnLinux que podem utilizar melhor as minhas aplicações e memória total?

Answer 1

Como você está determinando que a GPU só vê 384MB de VRAM?

É provável que apenas programas executados no Wine vejam 384MB de VRAM. Isso seria porque o OpenGL não ( ainda ) fornece qualquer maneira de consultar quanto VRAM tem um cartão, então Wine é forçado a adivinhar; pode estar adivinhando mal para você.

Para dizer ao Wine quanto a sua VRAM realmente possui, você deseja definir a chave de registro VideoMemorySize . Você pode fazer isso seguindo as etapas no UsefulRegistryKeys página do Wine Wiki, ou execute o comando winetricks videomemorysize=2048 em um terminal, que irá definir a chave de registro para você.
