它最初下载了一些图像并添加到库中，crashes.Is 因为下载的图像很大？我试图通过使用 webrequest datahandler dispose 方法释放大小，但没有 effect.How 来解决与内存相关的 issues.Any 指南？

看来你的贴图分辨率很高。此外，它们似乎未压缩。
纹理大小：6000 * 4000 * 4(RGBA) = 96MB

使用更小或压缩的纹理。最好在将图像上传到 GPU 之前降低图像的分辨率并进行压缩。理想情况下，纹理大小应该是两侧的二次方。这些尺寸如下：2、4、8、16、32、64、128、256、512、1024、2048 或 4096 像素。
