Yes, Diablo 3 can be installed on two PCs. The game allows for multiple installations on different devices as long as they are being used by the same account. This means that players can install and play the game on their primary PC and also on a secondary PC, such as a laptop, using the same account credentials. However, it's important to note that the game can only be played on one device at a time per account. **

The comparison of 3 gaming PCs can be based on their specifications such as processor, graphics card, RAM, storage, and cooling system. It can also include factors like price, brand reputation, and customer reviews. Each PC may have different strengths and weaknesses, so it's important to consider what features are most important to you as a gamer when making a comparison. Additionally, factors like upgradeability and future-proofing should also be taken into account when comparing gaming PCs. **

If you install Kaspersky Internet Security on 2 out of 3 PCs, those two PCs will be protected by the security software, while the third PC will remain unprotected. This means that the unprotected PC will be vulnerable to potential cyber threats such as viruses, malware, and hacking attempts. It is important to ensure that all devices are adequately protected to maintain a secure digital environment. **

Polyester is a synthetic fabric that is known for its resistance to shrinking. Unlike natural fibers such as cotton or wool, polyester is less likely to shrink when exposed to heat or moisture. However, it is still possible for polyester to shrink under extreme conditions, such as high heat in the dryer or hot water in the washing machine. To prevent shrinking, it is recommended to follow the care instructions on the garment's label and avoid exposing polyester to high temperatures. **

Polyester has both advantages and disadvantages. It is durable, wrinkle-resistant, and retains its shape well, making it a popular choice for clothing and home textiles. However, it is not as breathable as natural fibers and can be less comfortable to wear in hot weather. Additionally, polyester is a synthetic material made from petrochemicals, which can have negative environmental impacts. Overall, whether polyester is "good" depends on the specific use and individual preferences. **

Polyester itself is not inherently stretchy, as it is a synthetic fiber known for its durability and wrinkle resistance. However, when blended with other fibers such as spandex or elastane, polyester can become stretchy. This blend is commonly used in activewear, swimwear, and other clothing items that require stretch and flexibility. So, while pure polyester is not stretchy, it can be made stretchy when combined with other materials. **

Polyester itself is not inherently waterproof, but it can be treated with a waterproof coating or laminate to make it water-resistant or waterproof. This treatment creates a barrier that prevents water from penetrating the fabric. However, it's important to note that the level of waterproofing can vary depending on the specific treatment and construction of the polyester fabric. **

Fur is typically made of polyester acrylic, which is a synthetic material designed to mimic the look and feel of real fur. This material is often used in the production of faux fur products as a more ethical and sustainable alternative to real animal fur. Polyester, on the other hand, is a synthetic fabric commonly used in a wide range of clothing and household items, but it is not typically used to create fur-like textures. **
