Post From: Simple Replay of Multiple Charts on a High End PC lags in Accurate Trading System Mode

Hi SC,

I just tried another example which is even weirder... Please see below:

1. I have a SINGLE chart with ES loaded with data for 2 days (Continious Contract Back Adjusted Volume Based Rollover)
2. I select Accurate Trading System back test mode
3. I select All Charts in ChartBook
4. I select speed of 5
5. I select processsing speed in seconds to 0.01
6. Run

After this I still see the replay lagging, even though I just have 1 chart! If I switch back to Single Chart everything is ultra fast and smooth.

I have Tried both disabling OS Timers and enabling Sierra Timer Management to battle this, but nothing seems to work...

I really need to sync multiple charts and I know other people have done and I know I have enough compute to do it, I just don't seem to be able to get the settings right.

Let me know if anything in my experiments above sounds obviously silly.

All the best
