QEMU is a virtualization platform that runs guest VMs almost as fast as the host. I think to get those speeds you need to also run KVM but it's all free and open source, very easy to install on Ubuntu and clones. I'm not as familiar with some of the other distros but it's also reasonably simple to install on
Slackware14.2 and and clones such as Salix and Slackware LiveSlak Current (Alien Bob's build) may already have it although you would still need to install to a hard disk however you might be able to get the speeds you need by installing to a USB stick. either as a live system with persistence (although you may not need persistence I would think it's need ed to keep scores and perhaps where you are in the game
My hardware can't decide if it's USB 2.0 or 3.0 ... evidently Linux upgrades some of the servers to 3.0 however my USB thumb drives are 2.0 and the live distros that I have like Parted Magic and various rescue disks that run completely in RAM and boot as well as run very fast. With an SSD you get even more speed. Slackware installs on as little as 9 GiB for the complete system I've got a couple of copies of 14.2 on 50 GIB partitions and the are far from being full you can easily get Slackware on a 64 GB thumbdrive with all sorts of room.
With a live system you might get messages that running a virtual machine isn't possible but I believe that Salix and Alien's build of current will actually do exactly that if you have persistence, and SWAP enabled. I would think you might want SWAP enabled , even though some Live systems do very well at performance level processor speeds and for game play I'd bit the bullet and install the swap on either the thumb drive or the SSD.
I've been getting those 64 GB thumb drives for about 15 bucks and I think I remember the 250 GB Patriot SSD I most recently bought was about 40 bucks or maybe less.. With wear leveling technology being included in nearly everything now you should still be able to tolerate the costs and going to RAID with two or more SSDs you may be able to squeeze a bit more speed out of your installation.
A few months before I got the 250 GB SSD I purchased a 150 GB Patriot SSD for about that same price so it may be possible they're on a downward trend as both were on sale
You can still get use from a HDD, if it's a hybrid you may opt to try installing the OS to it and find you're happy with it but if you want to go with full SSD you can still use the slower HDDs for data where speeds aren't as critical.
I have 6 distros on that 150 GB SSD and probably could put at least two more, and even more if I set it up to boot the ISO files without installing as that is almost the same as running a live OS.
I don't run games so I have
SWAP on HDDS in several of my boxes to extend the life of the SSDs but Microsoft was swap (swapfile rather than swap partition) I belive file vs partition is equivalent performance wise but there are linux distros that also can run swapfiles if it turns out to have an advantage.... the point though is that MS seems to feel they can run swap on a solid state drive without killing it prematurely.
You may already know you shouldn't run defrag on solid state anything nor wipe it with a nuke disk. I believe that still applies as SSDs aren't constrained to the physical geometry like cylinders and partitioning schemes, etc which is one reason they are so much faster, fragmentation is irrelevant.
It would cost much to get a couple of USB thumb drives and/or SSDs, less than 100 bucks, Probably would be double that if you added as much RAM as your MB will stand and there are some Dells that accept double the documented amount as you can read more than a few hobbyist have found and are confirming.
You want a 64 bit OS but your software is free, and Windows is really bad about lying to you and claiming that a system board is 32 bit when in reality it's 64 bit, and you might have to change the setting to enable another core or something similar. I have two ancient Dell Inspiron 380 workstations that claim they don't have hyperthreading in the BIOS even after you enable both cores yet Linux rescue disks also so that the indeed do have such capability enabled, IMO either Dell or Intel was intentionally hiding that , this extra capability is also revealed on Dells support boards. With virtualization also enabled in the BIOs Standard Linux 64 bit distros run these two core CPUs as four cores. I think these were made about the time Intel was outed for having locked extra feature in some CPUs that you could pay extra to obtain the access codes, I'm not sure they are included in that farce. I've been meaning to research that deeper as I think there's an available crack for that and they may have released it officially but I don't see that . I may be that mine are the ones that they looked at and got the idea from . There are features that can be enable in the CPUS I have that are claimed to make them somewhat unstable but I've also read that it might have been a tactic to keep it secret. The newer ones that were released just after those are running that with no problems and the only way you'll (I'll) know.
Also 32 bit windows can only run up to 4 GB RAM but 64 bit on those same machines runs 8 GB and oddly 64 bit Linux using only 6 GB and a few using the the 8 GB that is the max for those MBs . That may be a consequence of my RAM for those being very slightly mismatched , I can;t think of another reason for that .
With Dell having undocumented RAM specs (mine aren't included in those) it's reasonable to think that other OEMs or even aftermarket MS might have similar secrets and if a person had the extra RAM to try in most cases if it was incapable of running it it would most likely not damage anything to try you would either find it would used the increased RAM, it wouldn't and only recognize the specified max, or you might get beep codes about memory so you would just remove that added RAM. (but try that last one at your own risk, might be worth it if ole stuff like I have )
