Why didn't mali864 perform better than mali764?
hello, I encountered a problem recently:
In EGL_BUFFER_PRESERVED model, under exactly the same hardware condition(CPU, memory, GPU frequency..), it appeared that mali864 only showed half the performance compared with mali764.
for mali864 I used android 6.0.1 in 64bit and the GPU driver version is r12p0-04rel0;
for mali764 I used android 4.4.2 in 32bit and the GPU driver version is r4p1-02dev0;
so, here are the questions:
1.what may be the reason why this happen?
2.would a newer GPU driver help?
3.what can I do to fix this?
That message shouldn't impact anything.
However I'm pretty sure that if you're seeing those messages and the memory histogram at all, you're running a debug build of the driver, which may explain the performance issues you are seeing. Can you try a release build?
If you are a licensee (which would make sense if you are using debug builds of the driver), you make get a faster response to your questions via support@arm.com.
