3600+,1G.7300GT.显示器931BW。

COD4分辨率一调到1440*900，就弹出对话框.显示

Couldn't create a 1024 x 2048 render target surface: Out of video memory

然后分辨率就变回640*480了，特奇怪，谁给看看？

Out of video memory

显存不够？

这英文不是说得很清楚了么……

好吧，这是完整的错误报告，请注意红字。

1440*900明明成功了~

好吧我就想知道为什么明明我选的1440*900分辨率她却给我弹出个“1024*2048分辨率无法支持”的错误框啊~~~

1024 x 2048 render target surface

是说某东东贴图的大小吧？猜的~~~

试试吧效果降低些？

总之他说显存不够是真的.....

1024*2048 的 RenderTarget 创建失败，原因是显存不够

应该是驱动中的问题，譬如你强制开启了某些画质控制之类的东西。

说起 RenderTarget （RT），是用来做后期处理的，景深啊，HDR的 Tonemapping 啊 都在这里完成 ……游戏会先把RenderTarget当输出目标，把这个当成屏幕。然后游戏再把这张画面“PS”一番最后贴在屏幕上。

恩，实际上如今游戏的分辨率应该用 RT 尺寸来说明才有意义 …… 而话说回来

1920*1080 这个分辨率是没法创建 RenderTarget 的 …… 理由很简单。长宽各自要为2的整数倍之外，长宽互相之间也必须是2的整数倍……真正 FullHD 的游戏，需要一张 2048*2048 的 RenderTarget ～ 或者 2048*1024 …… 稍微拉伸一点点。

当然，RT不一定要横着用，1024*2048 也行 ……

LZ要是128M显存的话，可能帧缓冲超了……是不是在驱动里强制打开了3倍缓冲之类的东西……

LS太强了！谢谢了！

上次玩的3D游戏是仙剑，驱动里开的8Xs，这次玩的时候没关……

lss好专业口牙

没可能,我就是1449*900玩的,128M的7300GT
