When different color transparencies overlap, sometimes the combined color is just one of the colours. For example when green and red overlap, instead of orange the color would be red or green

However what works fine is when same transparent colors overlap and they create a more opaque version of that color

Moving mouse marks somehow everything on the right, e.g. price of asset, values of indicators etc.

Click in chart region with crosshair, move mouse, -> marks the right of the screen, marks disappear with left click.

Current Version: 1957 (July 23, 2019)

In regards to post #26, this is already a known issue.

Using Win10 w/Radeon WX5100... enabled OpenGL. The fonts were different/difficult to read and appeared to be sluggish drawing charts. Disabled OpenGL.

are there any known issue with nvidia cards, or optimus? Or some min spec for the graphics card? settings tweaks? Usage limits in terms of how many charts it can run?

I have an nvidia 1050m 2gb. Even with just one chart (sized at about 1080p) there's an unuable amount of lag when i'm forcing it to use the nvidia card. Oddly i see both the integrated intel and nvidia gpu usage spike when i'm doing anything to the chart (like scrolling around). When using the integrated intel card only, the system is more responsive, which is very odd. Could be a configuration thing but i have no idea what it would be.

Performance chokes pretty fast with additional charts. When I run 1 of my normal chartbooks (which as about 8 normal charts, 1 blank chart, 1 detached chart, all fitted on a 4k monitor) the intel card is maxed at 100% when idle. I'm usually running 27 of these chartbooks at a time, which runs great non-opengl.

All the settings in the nvidia control panel are set to off or optimized for performance

In regards to post #30, is this when using the new OpenGL option and you have restarted Sierra Chart?

Just a Data Point....looks good here.

I have an AMD Ryzen 7 2700x processors and an Nvidia Geforce GTX 1660 Ti graphics card with two large monitors.
I have two chart books open and a large number of charts in each plus spreadsheets.


Without OpenGL processors utilization are:

CPU=3%
GPU=9-10% (very Stable)

With OpenGL utilizations are:

CPU = 3%
GPU = 10%-25% varying

Looks like work is successfully using GPU for rendering.

No issues noticed at all so far.

I did find one issue. The "Right Edge (centered) " Value label will not show when OpenGL is turned on in the studies in the lower chart regions. (version 1971).
The "centered" and "above" etc seems to be having issues also.

Works fine without OpenGL

Should OpenGL issues be posted here (like post 34)? Are the issues being logged for the developers? There are a few threads on OpenGL and one place to follow along with would be good. I'm very impressed with the performance BTW. The Chart update times have dropped over 10 fold on my computer. most charts say 1ms update, amazing.

Yes post any issues here but in many cases we will not respond. We are monitoring the thread. This feature is still considered a beta.

Regarding post #30 above:
1. Screenshot of Sensors tab in GPU-Z app when the problem appears and first tab on idle.
2. Attached Chartbook. Perhaps there is some specific settings for studies/chart
3. how many displays do you have?

Also the user may try to reduce screen resolution to 1600x900 or even to 1280x720 to reduce usage of video RAM.
If you need help with GPU Z let us know.

Certain text isn't showing on screen. For instance, I cannot see the DOM quantities when Draw DOM Graph on Chart is enabled. I also cannot see the number box in bottom right hand corner that tells you bar spacing.

I am also getting laggy user interface when moving charts around or scaling charts using NVIDIA GTX 1060. I don't experience any of this when using the integrated Intel graphics card. The NVIDIA card gives much faster chart drawing times though.

latest opengl updates have worked nicely on chart drawings and transparencies mostly, but I'm getting some new issues after charts have been running for some time. Drawings or studies using transparency with set colours like blue/red etc, the colour changes to black and they are not clearly visible any longer. This happens on some charts in the chartbook, not sure if it only affects some charts or all

Also sometimes a chart will just go black completely and nothing is on it at all, just black background. No bars/text/anything. I'm using 1984

more details on #40 to help debugging: When the left coordinates are out of view for a certain duration, the color changed to black. Condensing the bars so the left coordinates becoming visible, the filled color changes back to the its original color.

post #40. I just cut an extended rectangle on a non opengl instance and the same thing happened but only on the single extended rectangle, so maybe the issue is not opengl related

We are aware of this and this affects text on all drawing tools . We will fix this.

Just curious, are OpenGL fixes being added incrementally with new Sierra versions or will they all come at once when announced?
[2019-09-08 04:16:26]
Sierra Chart Engineering - Posts: 104368
Yes they are added incrementally . You should always be running the latest version if using OpenGL.

I've got 2 GPU's in my system, nvidia 980 GTX and an nvidia 1070 GTX. The default GPU is the 1070 which is about 1.3x more powerful than the 980. In the nvidia control panel I can select which GPU Sierra is assigned to for OpenGL and CUDA. If I leave it on the 1070 sierra runs great and the GPU load is about 33%. I tried to assign sierra to the 980 however (for CUDA and OpenGL) and it's unusable. The load on GPU varies every couple of seconds from 50-90% (in task manager) and makes the whole system sluggish (windows 10 latest). The difference in GPU load doesn't make sense as I would expect it to be around 50-60% max on the 980 given the difference in capabilities of the GPUs.

Not sure what's causing this. Maybe the 980 isn't supported yet or not optimised. Or maybe I'm not setting everything needed up to use the 980 correctly?

Are optimisations expected down the line? btw i'm running 1986

Our initial thought about those users who are noticing performance issues with a particular GPU is as follows:

Do not tell the operating system what GPU Sierra Chart should be using. It needs to make that decision itself.

And a particular chart must not be contained in more than one display. If two or more displays a chart is contained within are driven by different GPUs, you would create a situation where there are inefficiencies because the operating system has to start transferring resulting output between video adapters.

It is not efficient to have GPU do the rendering, and then have this output transferred to another display which uses a different GPU.

The above statements still have to be technically confirmed by us, and are just at this point only a logical conclusion.

------
When changing which GPU Sierra Chart is assigned to, you do need to restart Sierra Chart so there is a re-initialization of OpenGL on the Sierra Chart side.

Hi support,
Not a technical issue, more an observation when using openGL.

Personally I am now finding line width 1 to be not much use for anything other than solid lines.
The line is either bordering on being invisible (in the case of dotted line) or it's difficult to quickly distinguish between dashed, dash-dot & dash-dot-dot.

If don't know if other people see it the same, or maybe it's just me and I should invest in new glasses (or use wider lines).
