Legacy Display Mode Deprecation Plan
Note: The vast majority of customers are not using Legacy Display and so this probably does not apply to you. But check just in case.
With the launch of Alibre Design 2019.0 on July 22, 2019, we introduced a next-generation graphics pipeline. This pipeline allows us to create many exciting features that were not possible with the older pipeline. It also provides more consistent performance, especially for large assemblies.
To fully take advantage of the new pipeline, a reasonably recent graphics card was needed - something made in the last few years, depending on the size of your models. To give customers and add-on providers time to migrate, we kept the old pipeline around and called it Legacy Display mode.
Support for Legacy Display mode will have an end-of-life with the launch of v25, scheduled in the first few months of 2022.
The System Option called Use Legacy Display will be unavailable as of v25.
Legacy Display will be deprecated with the launch of v25. v25 is scheduled to launch in the first few months of 2022. As we approach the launch, a more definitive timeline will be given.
What is the implication of this change?
All customers using v25 (early 2022) or later versions must use the new graphics pipeline. v24 (end of 2021) or earlier versions will continue to support Legacy Display mode.
If you use Legacy Display mode for any reason and plan on migrating to v25 when it is available, you may need to consider a hardware upgrade if your performance is not acceptable.
If you are using any add-ons that require the use of Legacy Display mode and you plan on migrating to v25, you should upgrade the add-on to a version that works on the new graphics pipeline.
1. Determine if you are using Legacy Display Mode.
Open Alibre Design and go to System Options > Display > General. If Use Legacy Display is checked to on, then you are using it and therefore you are affected by this notification. If it is not checked on, you can ignore this.
2. If you are using Legacy Display, try turning it off and working on some modeling tasks.
You might be using Legacy Display unnecessarily. Disable it by unchecking the option and then restart the software. Open some models, perform some quick tasks like making a drawing, creating a sketch - and see if you notice a performance difference.
3. If you do suffer a performance decline, consider hardware upgrade options.
The new graphics pipeline is generally more taxing on a graphics card than the older pipeline. However, any graphics cards designed for CAD or for gaming made in the last few years should easily overcome the extra load. If your graphics card is very old, you may need to consider an upgrade. Your monitor's resolution and your Windows Scale Factor also determine the load on the graphics card, so if you're trying to run a 4K monitor at 100% on a very old card, you're going to have issues and should consider upgrading your graphics card.
4. Are there any suggestions?
Try to avoid using an integrated graphics solution. You want to use what is referred to as a "discrete graphics card", which is a totally separate piece of hardware that is only used for graphics. Many laptops use integrated graphics, so if you're laptop shopping ensure you find one that has a discrete graphics card made in the last few years that is designed for graphics work and/or gaming.
If you use a desktop, it can be much easier to upgrade just the graphics card. Find a graphics card designed for CAD or graphics design or gaming that is within your budget, and then consider whether the power requirements of the new card exceed your power supply's rating. Modern cards can use more power than older cards, and power supply ratings are often overlooked.
