| 34 | 34 | -[no]multithreading / -[no]mt |
| 35 | 35 | |
| 36 | 36 | Enables multithreading within MAME. At the moment, this causes the |
| 37 | | window and all DirectDraw/Direct3D code to execute on a second thread, |
| 38 | | which can improve performance on hyperthreaded and multicore systems. |
| 39 | | The default is OFF (-nomultithreading). |

| 152 | 154 | ----------------------------- |
| 153 | 155 | |
| 156 | -[no]filter / -[no]flt |
| 157 | |
| 158 | Enable bilinear filtering on the game screen graphics. When disabled, |
| 159 | point filtering is applied, which is crisper but leads to scaling |
| 160 | artifacts. If you don't like the filtered look, you are probably better |
| 161 | off increasing the -prescale value rather than turning off filtering |
| 162 | altogether. The default is ON (-filter). |
| 163 | |
| 154 | 164 | -prescale <amount> |
| 155 | 165 | |
| 156 | 166 | Controls the size of the screen images when they are passed off to the |

| 191 | 201 | -gl_glsl_vid_attr Enable OpenGL GLSL handling of brightness and contrast. |

| 302 | 312 | -audio_latency <value> |
| 303 | 313 | |
| 304 | 314 | This controls the amount of latency built into the audio streaming. By |
| 305 | | default MAME tries to keep the DirectSound audio buffer between 1/5 and |
| 306 | | 2/5 full. On some systems, this is pushing it too close to the edge, |
| 307 | | and you get poor sound sometimes. The latency parameter controls the |
| 308 | | lower threshold. The default is 1 (meaning lower=1/5 and upper=2/5). |
| 309 | | Set it to 2 (-audio_latency 2) to keep the sound buffer between 2/5 and |
| 310 | | 3/5 full. If you crank it up to 4, you can definitely notice the lag. |

| 317 | poor sound sometimes. The latency parameter controls the lower threshold. |
| 318 | The default is 2 (meaning lower=2/5 and upper=3/5). Set it to 3 |
| 319 | (-audio_latency 3) to keep the sound buffer between 3/5 and 4/5 full. |
