AMD APU UMA Auto 和 UMA Game Mode 分配内存

微星 核显默认设置为UMA Auto,该参数设置默认分配512MB给核显
将核显默认的UMA 修改为 Game Mode 分配核显 4G (主存32G)

11

有大神知道,两个设置的利弊吗?

本来也不纠结的,昨天试了一下 Adobe 的平面软件,如果 UMA Auto 只分配 512, 好几个软件没法识别 GPU加速。
开启 UMA Game Mode 后,就能 GPU加速了 感觉速度快一点。

但是: 核显使用 uma game optimized 后, 使用跑 AI 画质增强选用 realesrgan-x4plus 模型,
运行会错误,提示 vkallocatememory failed -2 使用 UMA Auto 能跑完

然后试了我 另一台 2年前买的 AMD 5700G 也是这样的情况的
