I was launching up Minecraft and noticed that the game was extremely laggy and stuttery (EDIT: It says my frames are really high in this screenshot. However when moving around a lot and loading chunks,etc, the frame rate becomes very erratic.) I opened up the pie chart and noticed that the percentages of the gameRenderer section of the chart were way too high. I have provided a screenshot for further explanation. Now, my game was running buttery smooth a couple days ago. My computer specs : 3.20GHz Clock Speed, Nvidia GT 720 GPU, Intel i5-4460 CPU, 8 gigabytes of ram, and the PC is 64 bit. I am also using the latest 64-bit Java 8 version, being "Jre-8u101-windows-x64.exe". I also have 3 gigabytes allocated to Minecraft, as you can see in the screenshot. Here is the paste bin link to the game log up to the point where it was giving the errors. http://pastebin.com/hWdE9mHw You may notice it says I'm using Optifine. This issue is happening on ALL versions I play, modded or not, so, in my eyes, it would belong in this forum section. I also want to mention that I am using a clean install of Minecraft, (backed up beforehand) so it can't be potentially corrupt files. The log also continuously mentions "Something's taking too long!" and either "'root' took aprox 'NUMBER'" or "'root.gameRenderer' took aprox 'NUMBER' ms". I have no idea what this could entail, but I hope the solution doesn't require any drastic measures. Thanks in advance for the help! :-) EDIT 2 (I also have tried installing Java 7, and the problem still persists)
If you are going to paste fragments from a log it would be easier to just use [ spoiler ] tags here.
The earlier part of the log is missing where the OpenGL discovery goes. The only interesting thing at the top of the log is the error loading OpenAL which would tend to indicate that your minecraft install has become corrupted. As this is a clean install... perhaps anti virus software is incorrectly preventing access to files or the re-install simply isn't as clean as you think.
---
Of note, and excluded here, is the fact that originally this problem started with a Windows Action center error "This application has been blocked from accessing graphics hardware". Which makes it sound like some part of your video driver stack has permanently added java.exe (probably) to a blacklist and minecraft is now being silently redirected to software openGL.
Given that this application blocking feature of the drivers seems to be entirely undocumented it seems unlikely that the NVidia control panel is going to have a handy list of blocked apps that you can peruse and unblock...
These things tend to be stored in the registry, so searching that for any instances of "java.exe" (or whatever executable is actually hosting your minecraft JRE) might yield some result.
OpenAL didn't load, but upon doing the F3-T keystroke (reloads textures and sounds) the sound came back, as you could see later in the log where it said the sound engine started.
I can definitely see that java.exe could have been added to some sort of blacklist.. I checked the Nvidia control panel, as well as the Geforce experience program. I did not see anything looking like a blacklist.

The problem with that location is that is the full path to the java executable, so a different version of Java should not have had the problem.
Assuming - or at least attempting to exclude the possibility of an outright hardware failure that would necessitate a replacement of "something" there is a matrix of possibilities to work through:
The "Application has been blocked..." message indicates to me that some hardware sensor tripped and in an effort to save itself the video card (via its drivers) has disabled the offending application.
The two things I can think of that would cause this would be heat or current related: double check that card for dust bunnies and stuck fans, make sure they all actually still work. Is your power supply sufficiently overspecced for your machine? The CAPs in PSUs age over time and their ability to deliver their rated current drops. You can calculate the theoretical draw of all the components and compare it to the listed rating of your PSU to be sure there is a 20% "buffer".
Perhaps its just a weird issue caused by OS (drivers) and your specific motherboard and video card: I don't know how easy it is to perform a clean install of Windows 10 - perhaps a dual boot to Ubuntu would allow you to test how minecraft (which is a java application) performs under a different Operating system and driver stack entirely.
So, things I'd try (in no particular order):
* clean install of Windows 10
* If I had a 2nd HDD, Id try a re-install of an earlier windows version, or Ubuntu (or your Linux GUI of choice) just to see
* Borrow a different graphics card - perhaps the card actually is faulty.
* Borrow a different PSU - perhaps it is caused by an undervoltage caused by aging components. This would tend to manifest as things heated up.
* blow the dust out of everything and check that all the video and power related connectors are properly seated.
* "downgrade" to a much much earlier version of the nvidia drivers.
* go into the BIOS and reset all the settings to defaults to ensure I didn't once choose an odd timing for something.
* Close chrome - especially if there are any windows with the Flash AX control. Having Flash open in chrome has caused my MC in the past to close abruptly with very strange OpenGL errors.
Practically speaking I have experienced machines with faulty PSUs and the FlashAX thing. I thought the faulty PSU was driver issues, OS issues and BIOS issues for the longest time.
I cleaned the GPU with some compressed air and got rid of any dust. The problem persists. The PSU is definitely enough for the GPU, as it was working around 7-8 days ago. I also would not like to do a clean install of Windows 10 because, yeah know, I have data and stuff on here. I know I could back it up to an external drive, but I don't want to take as drastic of measures as reinstalling the OS unless I need to. I was also thinking the issue could lie in the Anniversary Windows 10 update. I may try to downgrade Windows versions. The GPU could be faulty, yes, but I think that is around the same level as reinstalling the OS : last resort. Also, I don't trust myself playing with the components inside the computer. I feel like I'll accidently break something. Why do you suggest specifically downgrading to a *much* earlier version of the Nvidia drivers? What do you mean by "Go into the BIOS and reset all the settings to defaults to ensure I didn't once choose an odd timing for something"? I had Chrome closed for the majority of the tests that I did with Minecraft open.

Depending on your budget - or the availability of an older computer you don't care so much for, a 2nd operating system can be as simple as taking out the existing hard drive and putting a new one on. Also, the ubuntu installer can install ubuntu into a file on your windows partition (iirc) so you can safely try it side-by-side with windows without damaging your windows install.
WRT installing an earlier version of the drivers -the older drivers don't have as many performance optimizations. This might make things a blit slower, but should allow the card to run cooler, and if a driver update is what caused this problem to start now, going back might naturally move things to a point of greater stability.
The BIOS is a system menu that can be accessed before the operating system boots. Typically you press F2 or F9 shortly after rebooting the system while it is still counting memory, and before any messages from the operating system appear.
Really however, at this point, what we know is that "something" is wrong with your PC that is not wrong with other ... similar PCs. (Given the trickle of this error on forums we find in google that span the the last 5 odd years). The only way to solve this is to get brave with the screwdriver, and install CDs. Because the only way to find this kind of problem is to keep on swapping things out until the problem goes away - the thing you last swapped being the culprit. I suspect that everyone who has had this error has had a different underlying cause.
I don't have another capable enough PC to install Ubuntu onto.. it's around 6 years old and hasn't been touched for a while...
I tried installing much older drivers, but the issue still persists. I am going to re-upgrade the drivers.
Apologies for straying a bit off the topic, but I did notice something rather unusual. In the F3 screen, I noticed that it said "CPU 1x", while, before this issue came about, it said "CPU 4x". Here are some screenshots. I have to link to Imgur because of the less than 1GB rule. http://imgur.com/a/XDxG3 (scroll down to view other picture.) I really hope this has something to do with the problem and can hopefully lead to something..
Hello - I was messing around and I remembered seeing an option for the computer to boot with a certain amount of cores. I went to it (msconfig) and unchecked both top boxes, and, what do ya know? It is fixed Thanks for all the help.

Okay, so what do you think I should do? Should I try Java7..?

Just googled what that means ;-P
