after changing my videocard from gtx470 to radeon7970 ive started to get fatal error on houdini start.
“4424: Fatal error: Segmentation Fault

Saving application data to CUsers/me/AppData/Local/Temp/me.4424.hip
”
any ideas?
tried to reinstall - same thing.
win8 64b
build 623

still nothing?
kinda sad

hi,

From this thread thread [sidefx.com] it s perhaps a driver ‘s problem.
Try to test different version. ( use DriverSweeper to clean all your ati driver between two install)

I dont know if Sesi and Ati communicate their respective bugs but have chosen to develop on Opencl rather than cuda, implicate i think to exchange with all protagonists (nvidia and … Ati )

I really interested if you resolve your problem, to have your feedback about this ati 7970 with houdini.
For the moment the better choice (for low budget) is a gtx 580 3go, but the more i learn about the nvidia ’s performance and policy the more I want buy an Ati card.
The nvidia restricted drivers on opencl and opengl to preserve their sacrosanct quadro, put me angry !
sorry nvidia

Anyway have fun with houdini, (when it will start )
Thomas

thats why i bought Ati card.
thanks for the link.

installed stable build 581 and everything is just fine!
yay!

hey cool !

can you test your viewport fps in this thread [sidefx.com] ?
And if you activate opencl in pyro solver how is work ?

thank you
Thomas

it still crashes.
seems like driver problem.
should wait for new ver.
btw 3ds max, maya and xsi are working nicely

working fine in H11 viewport mode.
when setting to OGL 3.2 - immediate fatal error

how about opencl activation on pyro solver ?

papi
how about opencl activation on pyro solver ?

driver stops working.
i dont know maybe its because im on windows 8 and installed drivers for 7.
ive tested my card on luxmark OCL and it working fine and with no errors.
i just want normal viewport in houdini and its not working

I m not sure using Windows 8 is the best idea.

Nobody else here use an ATI 7970 to have some feedback ?

Have fun,
Thomas

swiched to gtx680 4gb and everything is fine now
