NT8 "Stops Working"

[CamNel03]

My NT8 continues to stop working. Can't seem to figure out what is causing it to do this. I completely deleted workspace and rebuilt and everything seemed to be running smoothly until later and it did it again.

For those with AMD video drivers

I had the same issue since the first public beta and had to check in to a mental hospital for a while, but eventually I traced the cause using process monitor utils.

If you have an AMD video card and install their driver bundle, by default it installs something called "AMD Gaming Evolved" which includes a crapware component "Plays.tv" for directx game screen captures.

NT8 uses SharpDX for rendering and the crapware above apparently thinks you are playing a game and tries to interact with your dx session once in a while, causing NT8 to crash before it has a chance to capture any logs.

Uninstalling "AMD Gaming Evolved" from the driver bundle eliminated 100% of what appeared to be random NT8 crashes.

Thank you for providing this information, mindozas. While we still will not know if it is related to what the OP experienced, this information may be valuable to other users and may help us improve Ninja 8's DirectX interoperability.

Thank you!
I had the same problem. Works fine now.

crashes while running strategy analyzer

Hello,

I have a issue with crashing of the NT8 all the time. I am trying to run genetic optimizing and NT8 is falling down all the time. I have set 500 000 samples and it reach e.g 500 and crash. Then I reduce it to 50 000 samples and same results.

Also when I am entering variables to backtesting and optimizing it is extremely slow. Sometimes when I manage to save variables for strategy analyzer and I am calling saved template it is not working and you need to change at least data series or some other variables to force NT working.

When running optimizing in mode default, it crashes again and it is showing remaining time like 100 009 day. When I used optimizing in NT7 same size sample required about 15 hours to calculate.

My question is if there will be some significant bug correction for strategy analyzer? In the current state it is not the best one as I was used to have it in NT7.

Thank you
