<div>Hi all,<br>
<br>
I am trying to use a Radeon RX 5700XT via OpenCL with kernel 5.3.0 (I have also tried kernel 5.3.18) on Ubuntu 18.04. I have noticed that this combination is much slower than expected. I'm trying to find out why, and how to fix it.<br>
<br>
If I'm in the wrong place to ask, would you be able to point me in the right direction?<br>
</div>
<div class="x_protonmail_signature_block x_protonmail_signature_block-empty">
<div class="x_protonmail_signature_block-user x_protonmail_signature_block-empty">
<br>
</div>
<div class="x_protonmail_signature_block-proton x_protonmail_signature_block-empty">
<br>
</div>
</div>
<div><br>
If this is a known outstanding problem, a reference to a bug or something else that would let me dig into it would be great.<br>
<br>
Thanks<br>
<br>
Josh Fuhs<br>
