device local mem size is too small, use anyway?

[freeroute]

Hello,

Today morning I installed the recent version of hashcat (3.00-3)

Running benchmark, I got this message:
root@The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali):~# hashcat --benchmark
hashcat (v3.00) starting in benchmark-mode...

OpenCL Platform #1: Mesa
========================
- Device #1: WARNING: Device local mem size is too small
- Device #1: NV86, skipped

OS: The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) 2016 Rolling, fresh install from repository(*.deb).
Video controller: 01:00.0 VGA compatible controller: NVIDIA Corporation G86M [GeForce 8400M GS] (rev a1)

NVidia driver, CUDA not installed yet, only nouveau, mesa driver.

But previous version (2.00-0kali3, nouveau,mesa driver), there was no error message.
root@The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali):~# hashcat --benchmark
Initializing hashcat v2.00 with 2 threads and 32mb segment-size...

Device...........: Intel(R) Core(TM)2 Duo CPU T5450 @ 1.66GHz
Instruction set..: x86_32
Number of threads: 2

Hash type: MD4

....

So shall I buy a new video card or could I use somehow (use CPU, not GPU), ignore the error message?
Or installing from source package maybe will help me?

Thanks,
