libccurl, win64, Intel Core i5 Graphics issue

[mettenian]

using libccurl to process a tx takes significantly more time on Intel Core i5 Graphics then without using GPU support. I checked libccurl with a AMD Card, and it is very fast, using CPU only is fast too, but using the integrated intel i5 graphic is very slow (GPU usage is >90%, monitored with SIV64X).

processing a simple spam tx (mwm 15) took <4 sec on CPU, ~1 sec on AMD RX 480, but >20 minutes(!) on Intel Core i5 Graphics

Can you try sharing the out put of clinfo so that I have an idea of what kind of architecture is there?

On my Surface Pro 4 (i5) attaching or sending never finishes.

iotaledger/wallet#116 => I was not able to attach an address to the tangle. I have a Dell XPS 13 9350 with an Intel HD Graphics 520

Thanks to rage1337 on iotatangle.slack.com I could resolve my problems by updating to the newest Intel driver.

Now everything works fine with the IOTA light wallet.

Unfortunately I can´t test that on my surface since it won´t let me install generic graphic drivers

[ghost]

But I also have the Intel HD Graphics 520

https://communities.intel.com/thread/115377 (Surface Pro 4). Worked for me.

same issue here with Intel HD Graphics 530 1536 MB, 2,9 GHz Intel Core i7 and on OsX Sierra 10.13.4. How can I switch to CPU?

[mehranshakeri]

@mettenian How did you use only CPU?
