for a project i have to remake the game "Donkey Kong", i have done most of it, but for some reason the game is slow "laggy" on my gaming laptop (10-40 FPS). On my desktop computer it runs fine (+100fps). Is there a way i can fix this?
The processor on the laptop is almost twice as fast as the one on the desktop, and the laptop has 2GPU's an integrated and a dedicated one. Thanks.
Thanks for the answers! I actually had the 6.12 version on DrRacket on my laptop, I tried downgrading to 6.10 and this fixed the lag.

I find when I run create react app on my laptop then begin to code in VSCODE my laptop heats up a lot more than usual to the point its burning to the touch.
I have a macbook pro 2018 macos mojave fully upto date i5 8gb ram.
Is the reason for this low ram of 8gb?
Any information would be amazing.
Thanks

Not sure what to try?
npx create-react-app
Not expecting laptop to get unusually hot. Only happens when running create react app. also sometimes happens when running Atom IDE but does anyone even use that anymore?
No, the amount of ram you have should be more than sufficient to to VSCode and a create-react-app. Ram also has little impact on heat so I don't think that is causing the issue.
What you could try is to open the activity monitor to check if any processes are using more CPU than they should. Also check under the Energy-tab, that could give you a good guidance to what is causing your heating problem. As an example, I've had problems before where some of my VSCode plugins have had a bug that causes them to run at 100% CPU constantly.
I am developing a .NET application, and have the luxury of doing this on a fairly powerful desktop PC. I want to ensure it runs okay on PCs with much lower spec, but I don't have spare machines kicking around and can't really afford to buy them. Is there any way to simulate a lower-spec PC on my current PC, to get a feel for how the software might run?
Any help or advice would be very much appreciated.
*My PC is Windows 7 Ultimate 64-bit with 8-core Intel i7 and 16GB RAM.
You could install VMWare and install any OS you want, with any hardware specs you want, provided that they don't exceed your current working hardware of course.
Keep in mind that VMWare is just a virtualization layer. It emulates an OS but you are still running your code on the same i7.
http://www.asp.net/mobile/device-simulators Here is an example of several Visual Studio plug-ins that emulate devices. You can also install Windows 8 and run hyper-v. It's great for this kind of thing.
So I have a few issues with Eclipse and Android Dev Kit.
First of all Eclipse is being unbelievably slow and sometimes it renders it really useless. (It even lags switching the tabs!!!.)
I tried modifying the .ini file and tried allocating it even as much as 2gb-3gb ram. Still no improvement.
Is there any way to get it up to Visual Studio efficiency? When I'm debugging and I want to view a value inside a class in the watch it lags to display a simple 2 digit integer! Seriously W*F is up with that? VS instantineously displays 100s of objects in a collection with no lagging.
Also debugging is really slugish and it is really annoying! Steping from one line to another takes about 2 seconds!
My laptops has this spec:
Core i7-2670QM 2.2GHz (turbo up to 3.1GHz)
8GB DDR3 RAM
500GB HDD
GeForce GT630M 1GB (Dedicated)
This laptop handles some of the most demanding software and games without an issue and Eclipse lags!
Another issue, when I launch the Android Emulator my sound drops by around a half (for everything.) I use the internal sound card (integrated.) Any idea of how to fix it?
Thanks very much

I fixed the issue after deleting everything to do with Eclipse and installing the x86 version instead of the x64 and the performance is a LOT better now!
It must be a design fault in the IDE.
Pretty much as the title says, using bootcamp.
WDDM1.1 compliance and GPU recognition confirmed by the WP7 emulator running with EnableFrameRateCounters showing.
I'm considering a Macbook air as a compromise to resolve a need to access iphone dev tools and upgrade my Win7 mobile capability to something reasonably performant with one device.
My current laptop barely runs Win7 and borders on unusable for WP7 tooling hence the interest to try and solve two problems with one device - if realistic.
I assume if the device can run WP7 tools satisfactorily, it would be capable of anything else I might want to do when booted under Win7.
The new MacBook Airs do not have very powerful processors. The 11" maxes at 1.66 Ghz, while the 13" maxes at 2.13 Ghz. However, they do have the same GPU as the current 13" MacBook Pro. Also, since they use solid state drives, data access is significantly faster. Overall, it will not be the fastest computer you've used, but it should be enough to work.
I've bought one, but since it's going to the wife, I won't be able to test it in depth.
Instead, the MacbookPro 13" from '09 works fine (monoTouch+iOS dev and bootcamp to vstudio+wp7 dev). I upgraded to 4 gigs memory and that helped, also the disk is slower than I'd like. It responds like a mid-grade desktop, imo.
The problem I see is that the processor on the air's is ULV with a really slow clock, also the sdd in the base version is only 64g which is going to be cramped, I think.
Consider this: many Mac gamers install Windows with bootcamp just to have better gameplay experience.
That's because Windows have native access to the GPU through bootcamp.

So the answer is yes.
I run VPC 2007 on my Vista business laptop with 4 gig RAM. I use VPC to run windows XP and maintain a VS2003 web project. At first everything was great. I assigned the VPC 512MB and did my work as usual. I also run Resharper and Visual SVN. Lately, the act of scrolling in a page causes the CPU to spike above 50, sometimes near 100. This freezes my machine occasionally and is frustrating. Typing code sometimes does the same thing.
I have experimented with changing allocated memory, disk space, turning on/off the paging file, uninstalling ReSharper and Visual SVN. There should be no reason this thing is slow with all the memory I have on this laptop! I don't have anything running on it but VPC at any one time.
I'm wondering if I should just install VS2003 on my Vista machine and deal with any incompatibility problems.
Any suggestions?
Try VirtualBox.
VirtualBox is a family of powerful x86
virtualization products for enterprise
as well as home use. Not only is
VirtualBox an extremely feature rich,
high performance product for
enterprise customers, it is also the
only professional solution that is
freely available as Open Source
Software under the terms of the GNU
General Public License (GPL).
If it were me, I'd run the VS.NET 2003 IDE on Vista natively. Just check out this page with the problems you might have:
http://msdn.microsoft.com/en-us/vs2005/bb188244.aspx
As far as your CPU goes, it could be a video driver/display issue. Have you tried turning Aero Glass on/off on your vista machine to see if that changes things? Are your number of colors for your desktop the same both in the VPC and on your host? Have you updated your video drivers recently?
I recommend VirtualBox. Every time I use VPC I soon give up because the performance is terrible. I run VirtualBox with a Vista virtual PC allocated 1.5gb ram and it runs really well. In fact I don't really notice much slow down from running natively.
First thing I'd suggest doing is run Process Explorer and Process Monitor to find out whats really eating the cpu. If it used to run fine, switching to another VM might not fix anything.
I'd bet VisualSVN is the problem. I had the same problem on a dual-core system with 6GB of RAM. I eventually just uninstalled it because it kept crashing the IDE.
BTW, I'm running Server2003 64-bit.
You probably have VPC07 runnning the active vhd at maximum speed. Go to options on the console menu and change this setting to divide CPU time equally among all vhd's and your problems will disappear!
