游戏默认是高配置进入游戏 而且不一定能全屏 这里就需要改点东西

　　1.先找到这个东西2.到「C:\Users\使用者\Documents\Witcher 2\config\」裡面找User.ini

　　然后后不客气的删掉它...

　　2.然后运行Launcher ... 选第2像进入设置.. 把Show advanced options勾上

　　3.然后我就开始设置

　　- Texture downscaling: higher values result in lower texture quality.

　　材质缩减，越靠下的选项画质越低

　　- Texture memory size: sets the amount of graphics card memory allocated to textures. Larger values will decrease the amount of streaming that occurs in game and will make the game run more smoothly, but they can also cause the graphics card to run out of memory and even result in game crashes. Choose a reasonable value based on the amount of memory available on your graphics card.

　　为材质所分配的显存，开越大瞬卡越少，但是开太多了爆了显存的话可能导致游戏崩溃，越靠下的选项画质越高

　　- Shadow quality: affects graphics performance. Consumes GPU power without affecting CPU performance.

　　阴影细节，吃显卡而不是CPU，越靠下的选项画质越高

　　- Number of shadowed lights: set the maximum number of lights that cast shadows. Affects graphics performance. Consumes GPU power without affecting CPU performance.

　　光源数目，吃显卡而不是CPU，越靠下的选项画质越高

　　- LOD distance: distance scale for level of detail on meshes. Lower values improve game performance but result in reduced detail on models.

　　视距相关，越靠下的选项画质越高

　　- Bloom: effect greatly improves quality of game graphics without placing excess demands on GPU.

　　不是很吃显卡的提升画质选项，越靠下的选项画质越高

　　- Light shafts: visual effect recommended for medium-high/high-end machines. Should be disabled on older systems.

　　为中高端机器设计，越靠下的选项画质越高

　　- Anti-aliasing: demanding effect that can significantly reduce performance, so it should be disabled on medium and low-end machines.

　　抗锯齿，中低端机器建议关闭，越靠下的选项画质越高

　　- Blur effects: special blur and radial blur visual effects that are quite demanding on hardware but used rarely in the game.

　　模糊特效，吃硬件，越靠下的选项画质越高

　　- Depth of field – gameplay: subtle visual effect. Option determines appearance of effect only during gameplay sequences and does not affect DoF in cutscenes.

　　景深，仅游戏中生效，过场动画中不受影响，越靠下的选项画质越高

　　- Vignette: aesthetic option that produces a photographic vignette around the game screen. Does not affect performance.

　　装饰画面，不影响性能

　　- Rain, Wet surfaces rain effect: modest impact on performance.

　　雨落特效，对性能影响程度一般，越靠下的选项画质越高

　　- SSAO (Screen Space Ambient Occlusion): lighting effect that is important to the game but unfortunately places significant demands on the GPU.

　　很重要的光晕特效，但是很吃显卡，越靠下的选项画质越高

　　- Motion blur: blur effect on camera movement, demanding on the GPU.

　　动态模糊，镜头移动时生效，吃显卡，越靠下的选项画质越高

　　- Cinematic depth of field: provides movie-like depth of field in cutscenes and dialogue sequences. Extremely detailed but demands significant power. Should only be enabled on machines equipped with top-end graphics cards.

　　过场动画景深，过场动画时生效，特别细腻但是特别吃硬件，只建议顶级显卡的电脑开启，越靠下的选项画质越高

　　- Depth of field – cutscenes: option only affects cutscenes and dialogue sequences, does not affect gameplay performance.

　　过场动画景深，不影响游戏过程中的性能

　　- Dangling objects limit: limiter for physical animation of character components like Geralts hair. Disabling this option places greater demands on the CPU.

　　摇摆物体数目限制，限制人物身上可以摇摆的模型数目，比如说主角的头发，吃CPU，越靠下的选项画质越低

　　- Ubersampling: high quality rendering mode under which whole scenes are rendered multiple times to provide the best possible textures, object details and anti-aliasing (superior to anti-alias and anisotropy even on the highest settings). Use with caution, only on top-end computers (best possible in terms of both GPU and CPU).

　　超级取样，用于渲染游戏宣传已久的惊人画质，代价就是此乃最为坑爹吃硬件的选项，小心慎用，仅为顶级显卡和CPU设计，越靠下的选项画质越高

　　- Vertical sync: helps eliminate "screen tearing" during camera movements and blinking on very quick animations (e.g., bright explosions), but can cause somewhat slower rendering and short input lags.

　　垂直同步，如果开了就让帧数不超过显示器刷新率，解决斜纹问题。

　　- Decals: enabling decals like dust or blood on characters can affect CPU performance.

　　人物身上的尘土、血迹之类的特效，吃CPU，越靠下的选项画质越高

　　大家量力而为吧 中低端显卡 就开低一点 效果不会差到哪去..

　　4.最后最重要的一步..设置完以后点OK 会生成新的User.ini 双击打开 将[Engine] 改成[[Engine] 然后退出保存 在点右键属性 改成只读 就OK了.... 如果还想换配置 请重头来 删掉 在设置然后 在编辑......
