Description
Fields
|
Total: TGLint; |
|
| |
|
Current: TGLint; |
|
Total and current memory available, in Kb. May be zero if unknown (only some NVidia GPUs support this). | |
|
CurrentVbo: TGLint; |
|
Current memory free for a particular feature, in Kb. May be zero if unknown (only some AMD GPUs support this). | |
|
CurrentTexture: TGLint; |
|
Current memory free for a particular feature, in Kb. May be zero if unknown (only some AMD GPUs support this). | |
|
CurrentRenderbuffer: TGLint; |
|
Current memory free for a particular feature, in Kb. May be zero if unknown (only some AMD GPUs support this). | |
Methods
|
constructor Create; |
|
procedure Refresh; |
|
function LessTextureMemoryThan(const RequiredMemoryKb: Integer): Boolean; |
|
Detect GPUs with low texture memory. Looks at Current or CurrentTexture, whichever is available. This is useful to detect at runtime when to use e.g. compressed textures (S3TC and such) or downscaled textures (using GLTextureScale or TextureLoadingScale). | |
