你好，

我想强调，我希望在这里建立建设性的讨论，不像我在Synaptic Discord上看到的那样进行任何侮辱。

从许多YouTube视频，尤其是那些以高端电脑著称的YouTuber，可以明显看出Synaptic A220的优化并不理想，比如在A330Driver的视频中会出现明显的卡顿。我猜部分原因是A220没有原生的2024年版本。

能否详细说明你们对此问题的计划？我不认为像这样“小型”的客机有权表现这么高（比如说，和A380相比）。

谢谢！

Actually, if you watch swiss001's videos, you'll notice that he also experienced lag at London City Airport.

自从我买了这架漂亮的飞机后，最近做了一些测试。

我在Intel i7、RTX 3060笔记本上运行MSFS 2020。我在LDZD扎达尔机场进行了一次无AI交通的受控测试。

测试条件

• 机场、天气和图形设置都一样

• AI流量完全被禁用

• 玻璃驾驶舱刷新率设置为低

• 测试期间，两台A220 EFB均关闭

• 开发者模式 FPS 和帧时显示已启用

突触A220-300结果

• 重启后又冷又黑：大约31帧

• 显示和系统供电速度：约18–21 FPS

• 发动机启动/运转：约15–19 FPS

• 完全运行时，外部视角：约14–16帧每秒

• 完全运行时，驾驶舱视角：约15–16 FPS

• 滑行速度：约11英尺/秒，伴有严重的卡顿，使飞机极难控制

禁用两个EFB并未带来实质性改善。开发者模式始终显示模拟器被主线限制。

录制的A220帧时间大致包括：

• 主线程：39–50毫秒

• CoherentGTUIhread：20–37毫毫秒

• 操作手：21–28毫秒

• 显卡：14–15毫秒

在一次直接对比的动力驾驶舱捕捉中，PMDG 777-300ER的CoherentGTUIThread时间约为3.8毫秒，而A220约为21.2毫秒，约高出5.6倍。

相对较低的GPU帧时间表明显卡并非主要限制。

对照PMDG 777-300ER比较

我在同一机场用同样的模拟器设置重复了测试：

• 寒冷黑暗，外部：约40帧每秒

• 寒冷黑暗，驾驶舱：约33–34帧每秒

• 系统和显示全功能：约25–26 FPS

• FMC编程和正常驾驶舱工作流程：约22–23 FPS，保持流畅

• 发动机启动：约23–26 / /

• 襟翼5选择：约22–23 FPS

• 滑行速度：约17–20英尺/秒，流畅且无卡顿

• 完全配置并准备起飞：约20帧/秒，依然平顺且可控

• 在发动机、飞行动力学、起落架收回和自动驾驶仪激活状态下，飞行速度约为19–20 FPS，保持平稳可控

我成功完成了大约14至17小时的飞行，包括伦敦希思罗-珀斯、伦敦希思罗-东京、新加坡-洛杉矶、德里-伦敦希思罗和纽约JFK-法兰克福，使用PMDG 777-300ER、Horizon 787-9和iniBuilds A350。这些飞行包括平稳的进近和着陆，没有逐渐的帧率下降或严重卡顿。在我的测试中，这种性能下降程度仅发生在Synaptic A220上，即使飞机静止或滑行时也会出现。

A220在系统启动时，冷天和黑暗性能大约损失一半，滑行时帧率降至约11帧/秒，并出现严重卡顿。这似乎是飞机特有的主线程或系统处理问题，而非一般GPU限制。

开发团队能否确认是否重现了这种行为，以及目前是否正在研究更广泛的主线程和系统性能优化？

I'd actually been really looking forward to this A220 and Justflight F100 70 bundle all year, but since the A220, whose performance might not be particularly "impressive," was released first, I bought it anyway. Overall, I'm more disappointed than anything else. However, I could wait and see how it improves; otherwise, given the performance of my SteamDeck laptop, I might regret buying this addon for the rest of my life.

今天更新了“热修复”。在我认为还算不错的PC配置（7800X3D配4080 Super）下依然无法玩。在同样的设置下，Fenix A320、PMDG飞机等都非常光滑。这真是一团漏洞百出的烂摊子。

除了滑行、起飞和降落时持续不断的幻灯片，导致无法玩之外，今天我1小时内体验到了：

• FMS1 在 MFD 上崩溃（黑屏）

• FMS屏幕即使外接电源和APU运行也无法亮起

• 襟翼被阻挡

• 外部电源会自行断开，打开APU时导致所有MFD崩溃

  我理解团队正在努力寻找“能做些什么”来提升性能，但我花了70（70）美元全额性能来使用这个产品并享受它，而不是为了整天工作后做测试。如果“无能为力”会发生什么？

该产品现状显然远未达到可释放的条件。我的钱已经没了（市场不退款）。作为顾客，我唯一能做的就是表达我的挫败感，劝阻其他顾客购买这款产品，把我的生意转移到别处。Inibuilds商店在这个问题修复前不会看到我1美元的钱。

So let's wait together for Justflight's F100-70 bundle to launch on Marketspace. After all, they're both narrow-body regional jets, and it includes a delivery service from one of my favorite niche airlines (Air Niugini).

I'm really looking forward to today's update!

v1.0.3 is looking very promising in terms of performance. Let us know how it's running for you, once the update is live!

First impressions upon installing Update v1.0.3

• I was able to get it in the air without going to 12fps, great!

• It's still Stutter City, although performance has improved a lot.
  Running 30fps average up to 45-ish, but LOTS of random and frequent stuttering
  

This was a quick circuit spawning on the RWY. Gonna load up an FPL and see how it fares at a medium sized airport.
Going in the right direction, but to be frank, not near where I expect a 70,something-euro product to sit.

Really rooting for this to get better though!

If you have GSX Pro try in Config to disable the plane in question.

Thanks for the feedback! I'll make sure to pass this along to the Synaptic team.

Thanks! Thanks for the tip, I'll try that right now.

Thanks! Looking forward to seeing the progress on this baby

Update:

Loaded up a quick flight with my favourite green bois from EETN (default) to EFHK (MK) .
My experience was as follows:

I first loaded the A/C from an installed state. This resulted in the cabin consisting of our beloved pink squares. This problem disappeared when I uninstalled and went to streaming.

Ground: Nothing major to report. I did leave GSX off. Performance matches what I usually get during preflight. Manageable stutters during taxi.

Take-off and Climb: No major stutters on TO roll, stuttering around 1000ft

Cruise: 55fps, no stutters. No complaints.

Descent: Major stutters and fps crashes as I was descending into Helsinki. Sometimes it seems like it's loading something, cause then I am back to 39-46fps (overall my average across the sim. Still tiny stutters every half second, GPU limited.

Landing: Continuous microstuttering (flashing red fps counter), fine until 1000ft, then worse stutters and down to 22fps on landing.

Generally, switching to external is a big ouchy. FPS goes all red :')

I will be playing around more with settings and see what happens.

Thanks for the report. It seems like performance increases are there, just needs further refinement. Will report this to the Synaptic team (I'm pretty sure they are well aware by now).

Thanks!

Ladys and gentleman, try again with the "Community" folder empty, except for the in-game aircraft. If it works, copy the next item or a small group of them into the "Community" folder and continue testing. That way, you'll eventually track down the culprit.
That’s just my humble opinion.
