Why does Studio take so long to playtest?

I have quite a small project I’m working on, and I test it 20-40 times a day for bug fixes and updates. However, recently, I’ve been noticing that it takes extremely long to playtest the game. I click play, the window stops responding for 2-3 minutes, and then my game finally loads. Not only that, but this same issue happens on a blank game! I opened Task Manager, pressed play, and here’s all it’s using:

I’m pretty sure Studio isn’t 32-bit, since the RAM limit for 32-bit is 2GB, but it can be seen using more than that here:

If it’s 64-bit, it should be able to use as much of my 16GB of RAM as it needs, which confuses me on why it’s only using little RAM. Also, did you notice how little CPU it’s using? I have Studio added to my Game Mode settings on performance, and I have my computer’s battery plan set to best performance.
EDIT: Could my slow internet be causing this? Web pages always take 15-30 seconds to load, even the simplest ones.


The limit is actually 4 GB, and I’m pretty sure there are still some versions of Studio out there that are still on 32 bit.

I suggest you try re-installing Studio and Roblox as a whole, but it could also be because of your game itself or some weird plugins.

Also also, 13% CPU isn’t a little, it’s definitely doing something while it’s frozen. What are your specs? Make a bug report to @Bug-Support if this keeps happening.

I’ve seen it using over 45% CPU before

I have some 32-bit games, specifically Geometry Dash, and I had to install a 4GB patch for it to use 4GB. Maybe it could be just that game?

System: Windows 11 Home (64-bit, Windows 11 is only 64-bit)
Laptop: Acer Aspire 5
CPU: AMD Ryzen 3 with 2 cores, 4 logical processors (built-in GPU)

According to Wikipedia, 32-bit apps on 64-bit windows can use up to 4 GB of memory if configured correctly, but anyway this doesn’t really matter since Roblox Studio is 64-bit;


From my limited knowledge of AMD cards, that’s really the only weakpoint I can think of, but the specs you’ve given do seem a bit… sus. Personally, my laptop has 4 cores, 8 logical processors, but I can’t say that that’s the definitive reason you are having these issues.

Did this start happening recently? For example, after a Studio update, or after updating Windows? If it did, then it’s not your fault. Make a bug report to @Bug-Support, as they can actually forward your post to #bug-reports.

I hope you sort your issue out! I remember being in a similar situation to you, I use to have to wait upwards of 2 minutes because my poor Windows 7 laptop couldn’t handle Studio.

this wasnt the issue… it was the solution. my windows hadn’t been updated in forever and this fixed it
