Previewing Titles become only extremely slow when a shadow is added. Make sure not to use shadow in Titles&Text but use Shadow from Layer DimensionalityFX instead.

Titles are always slow and not having a GPU makes this worse. Highlight titles and do a preview with shift + b or shift + m?

Thanks for the comment. Shift m is what i was using as an alternative. Shift b seems better!

Oh thanks for the tip! I will try that next time!

@isanghao Be aware that preview resolution settings are also important for a lagging free preview. It makes no sense to preview in full resolution when preview screen has just a small resolution. Try setting "auto" instead.

Also make sure that your internal Intel GPU is used for GPU acceleration:

Shift+B will make a dynamic RAM based prerender depending on the resolution setting of the preview. the length of the possible preview prerender is dependable on the reserved RAM memory and the used resolution.

Shift+M will make a file based prerender based on the project settings (when not changed), the length of the possible preview prerender is not limited.

@isanghao No you're not missing something, on my machine i get a lag with the simplest of texts unless i do Dynamic ram or prerender & for the specs i have i would consider a fairly major lag, @RogerS @3POINT I know Vegas performance is an ongoing subject & sometimes a delicate one to bring up, but some of these 'laggy' issues really do need to be addressed soon,

@Former user Probably also hardware and used footage dependable. On my machine I have no lagging preview with titles together with 2160p50 footage. My preview settings is mostly Best-Auto. I only get (animated) titles lag when using the Titles&Text shadow. I seldom use a preview render (Shift+B od Shift+M).

I'm aware that Vegas preview is not ideal (compared to others like Davinci Resolve) and could/should be better, but Vegas has luckily workaround tools to get a lag free preview.

@3POINT 👍 Yeah 2160p 29.97p here, if i set it to Auto playback improves a lot but the res of the preview is noticeably lower, Good (half) is my preferred setting, I drop it to Auto when needed,

Yep the inbuilt text shadow seriously slows it down, i do as you suggested, i add a shadow using a different fx,

You have a decent i9 CPU & a good GPU, I feel for those with a more regular home PC & understand some of the frustration vented in some of the posts.

As said and shown before, it makes no sense to use a preview resolution higher than the resolution of the preview display. Ideally set the preview the same as the display size, than you will see no noticeably lower quality.

Do you see a difference in resolution below? But you will see a huge difference in performance!

Maybe also important to know is what the difference is of the preview settings draft, preview, good and best:

Read this thread: Preview Window Size (vegascreativesoftware.info)

@3POINT I don't really see a difference in your pics,

I'm on a 34" 4k screen, look at the small branches at the top of the trees, the small window blinds above 'In' & the wall next to it, the joint between white & red brick, & the edges of the text.

It might not be that clear on this forum but it's like a mild blur has been added, (Half) res is similar to (Full) for me,

@Former user From your screenshots I cannot see the size of your preview display. Of course when size of preview display is larger than resolution of the used preview resolution setting you will see a lower resolution when setting to auto. The size of your preview display and the size of the preview resolution setting can be read here:

Does it make sense to preview in full 4k for editing? It think it's more important to have a smooth less resolution preview than a full resolution non smooth preview. Also for full screen preview I would use the external monitor preview instead of making the preview screen full screen.

@3POINT size of preview are the same as yours in the pics posted, but the Display is bigger, why i mentioned i'm on a 4k 34" screen

when set to (Auto) the preview is smaller so some up res is applied & so loss of quality

& thanks & no offence but those things you point out are newbie things, i've been editing for 16yrs, i know those,

that's why i use (Half), the Preview is slightly bigger than Display so no up-res & therefore no loss,

'Does it make sense to preview in full 4k for editing?' - for the things i do there's not that much difference normally, I edit in 4k because my machine can handle basic editing no prob, it only really affects the performance when fx's are applied, it's very important to have a good res tho when any kind of colourisation or similar LUT/filter type fx is applied, I bought a decent PC so i didn't have to reduce this n that just to be able to use Vegas so I emphasize with others who have just paid a lot of money for PC equipment & then it doesn't seem to make Vegas playback that much better, esp if you try out other software where this downscaling isn't necessary, & as i say those with less powerful machines it must be a bit infuriating having to reduce the preview to a point where it's unwatchable just to get it to play. just like the orig OP who can't get a simple text to play.

BTW over the past yr I've tried pretty much all the main editing software on offer, I've had Magix Edit Premium since 2004, it doesn't cost much to renew each update, £40-ish, it plays 4k fluidly, & the other day i exported a 50min 4k project in 10mins, Vegas is def the slowest of them all, but MEP doesn't do all that Vegas does & doesn't support all my plugins so i still use Vegas & haven't been tempted to swap to one of the others, 🤷‍♂️

As i wrote earlier & hope 'some of these 'laggy' issues really do need to be addressed soon'

That's what I mentioned earlier, your display size is now set 1758x989, so auto will use a 960x540 preview and shows less quality the when using half which uses 1920x1080 (from 3840x2160). But when you resize your display just to 960x540, auto will give the same quality preview as half. On the other hand when you resize your display to 1920x1080 instead of 1758x989, auto will use 1920x1080 for preview which is the same as half.

A full resolution preview is indeed important when applying FX etc. But then you will pause the preview to judge the adjustments.

I'm using Vegas since version 5 also some 16-17 years now and tried also several other NLE software. For quick jobs I even prefer Powerdirector above Vegas. At the moment I'm teaching myself Davinci Resolve which offers definitely the smoothest preview and fastest rendertimes of which Vegas can only dream of. But I doubt that I ever will get skilled to the level of my Vegas skills. What I prefer about Vegas is the editing speed when using scripting possibilities like Vegasaur and the quality of the FX and the quality of the final render (when using Voukoder).

If Vegas ever will solve those performing issues, I doubt a little because I'm hoping this already for several versions. I'm afraid that this is also due to the old code where Vegas is based on. On the other hand I still see that Vegas is not fully using the power of GPU, which definitely has some potential to improve the speed of Vegas when addressed.

@3POINT Yeah, we're on the same page it's just hard sometimes to put into written words & dependant on each system 👍

'Vegas is not fully using the power of GPU' Yep definitely, I have a 25min 4k project i test with as my Youtube vids tend to be 20-25mins long, MEP exports in 5mins & uses 100% of my GPU, Vegas renders in 14mins & uses 1/3 of my GPU,

I have the free DaVinci Resolve only because it's free, I keep opening it & have a play but I'm not that keen on it, , MEP & Vegas have similar timeline workflows which i like, & i have Hitfilm Pro because it handles my CAD 3D OBJ files really well & can be opened in Vegas, but i then export or save & use in Vegas
